Can't record anymore

Hi everybody.
I am very frustrated, I'm sorry to say. I'll try to be as clear as possible. And I need help.
Last year, in August, my dear Cakewalk stopped working after I got a new computer, with Win 7.  After many email conversations with a nice lady (Kelly Brennan) at customer service, I got the new version and it worked properly until last week. I did nothing to change it but it doesn't record anymore. Curiously, I got several updates from Windows a couple of days before. Any relation?
Since then, I tried many options: re-install Cakewalk, check connections, soundcard settings. No changes.
What happens: it seems the needle of the turntable works because it catches all «movement» the arm makes before reaching the record. The second it touches it, there's no recording.
Now, I saw there is many updates here to download. Would it help me? I did the most recent one. It made an error, that I skipped. No changes.
I am very fed up. Making CDs out of 33-45-78 rpm is a hobby and it became quite a troublesome adventure. I think of simply buying a new kit (turntable + program, like Ion) and get rid of Cakewalk.
Despite my negative comments, I like Cakewalk because it's easy and does the minimum I need. Other programs need to be used through iTunes, and I am not interested...
I've nobody around me here to help me. I'm on my own, hahaha! Can anyone help me?
 

Yes, an AudioTechnica USB turntable.
Yes, I am using my onboard soundcard for playback.
 
Audio - Options says:
Playback device: headphones (high definition audio)  **** this seems new since the Windows update
Recording device: stereo 1 microphone high definition
Bit depth : 16 (very pale)   64-bit (not marked)
Sample rate: 44100
Driver mode: MME 32 bit
 
I played with that window many times. The  problem was there the 1st time.
 
Thanks for your answer.

Yeah, quite aware of that now... :-/

the windows 7 service pack one messed with me a little..i did it thinking it would help..even after a system restore..something is still up..i have three files that keep updating everytime i open sonar..aud ini..cntrlsurface and instrument something..now i do know those three files will update..but my aud ini file hadnt updated in three weeks..now it updates every time i open x1.

Beagle, sorry for my delay in answering this. The page stopped sending me notification that there was new messages. (sigh)
I'll try what your indications and tell you what happens.
THANKS for your help.

I don't think the download versus boxed version has anything to do with your problem, so don't spend more money trying that.
There has been a slew of people in the last few weeks with similar problems (can't record, select inputs, etc.). With no evidence to support it, I think it's Internet Explorer 9.

Bull****
Take your cheap knockoffs to the street, ******e.

Yes, Robomusic, I plug before starting Cakewalk.

Thank you EVERYBODY for all your ideas and advices. However, tried everything, it still doesn't work.
Too bad. I'll have to find another solution. Like a used little portable PC with Win2000 and the Cakewalk start-up CD. It worked for many years that way.

thanks again !

 Again, thanks everybody. Bought today another turntable that uses the Audacity program... SAME problemsssssssss. Ha!  So, as I guess it is my 1 ½ yr-old computer that has a sound card problem (what the F ...  can it be?) I'll try the new turntable at a friend's house soon. Thankfully, I can bring back the new turntable and have my money back if...

(I guess I simply wanted to put an update here... But I do wish I had somebody near me to help me. Sigh.)
