Hi, I have tried 3.09 again, Nogo, had to abort, resulting in another wind back to restore point with 3.08 on.Tried removing 3.08, nogo, same problem as 3.09, certain files missing, .So stuck with 3.08.+ now having AV trouble, windows Security centre not picking Avast/malwarebytes up. First time ever.Without restoring back to when I first put cc on , I,m stuck with 3.08. it,s even refusing to do restore points, had to abort several attempts.Either I have something on my pc ,or, cc has been corrupted all along.I,m going to do a Hijack this, see if anything can be found.Even revo half way through uninstalling 3.08 said "running the application uninstaller failed.Possible invalid uninstal command" Rather in a quandry at present what to do, apart from complete complete OS re-instal, which will be last resort.Will keep trying, any more advice would be grateful.Cheers.Until I can remove 30.8, I,ll defer on portable, but thanks for reply, much appreciated
