I just dont believe my bad luck Auto GK has deleted all of my downloaded files for some reason??

Is there a program that can find stuff deleted as it was without my confirmation to do so, as i'm really pissed off i have now 58.7GB, before that it was 10 GB about!

After searching around for the Xvid codec, i clicked on the Auto GK icon on desktop, it showed me it was corrupted & reinstall it!

So i proceeded to uninstall it & reinstall it from the main site, but it took an awful long time to uninstall when i came back a few mins later & noticed it was stuck with the 2 words close/delete & thought that weird on a folder it shouldnt be in as it was going thru all the files in Program files??,
so i tried to close the window & had to resort to Task Manager to do the job & just went to reinstall it over it, thought it might do the trick & it did, but when i went to find a file it said it wasnt there!

& that's when i found out /hand over face goin ohh nooooo!

This kind of thing really knocks you for 6 as i was getting around to takin stuff of the HDD.

SO if there is any program or/and on how this disaster happened.

I'm away to bed as its late here.

Thanks for any assistance given.
