Hi, first of all thank you for your support.
I unistall the Trend Pc Clinic antivirus and tried to work without any antivirus on my Dell, and with wi-fi disable. Even batter was kept out.

I am not able to work - record and play - to my project with audio Fx. Only bypassing them i can do something...it's very strange...

Maybe i have to try with another software to make a comparision...

What are your settings for saving your audio? Have you checked save audio in the same folder?
Im just guessing here a little.

I save audio in cakewalk projects...the same folder forse every project..with different name for every one of course..
