hi all  downloaded x2  as soon as it was released last year
it took hours,...halfway through install error message corrupt file came up 
skip this [not recomended] or start again.
so i cleaned everthing up including registar and started again
this time it went all the way through with no error messages
job done i thought
now iam not to sure  ,i get all sort of glitches and stuff not functioning 
 even after i installed x2a update
just been putting up, with it but should i, and can i download it again
  any ideas   cheers   phill

I hope my install goes OK.  I just downloaded last weekend.  

At the bottom of the X2 download instructions page are links to detailed information about the files including md5 hash values. You can use the md5 hash values with a tool like WinMD5Free to verify the downloaded files are correct. Also, if you are upgrading from X1 Producer, you may want to skip installing DimPro, the version that shipped with X2 is identical to X1.

Well, the first place to start would be to ask about settings and such.
 
1.  What Driver Mode are you using in Sonar?  (ASIO/WDM)
2.  What Sample Rate is set for the audio interface?
3.  What ASIO Buffer Size is specified in the audio interface's UI?
4,  What Sample Rate is specified in Sonar?
5.  What Record Bit Depth is set in Sonar?
6.  What are the reported latency values in Sonar (for the interface as well as total round trip)
7.  For your audio interface, what is the precise driver version you have specified?
8.  Have you tried running DPC Checker and/or LatencyMon - outside of Sonar, to get system latency values?
 
Please review and respond to the above, and I will try to assist
