Tried running the program as 'run as admin' before doing the patching?
Sometimes, you need to minimize the folder window and go in-out of it to make the size increase.
By the way....please be specific and detail. Making a post that sound like that is really annoying.
Why? Cause it's lacking in information. At the very least, do give the name of the patching program,
the patch file extension, computer OS, etc. You do expect an answer that help solve or at least
shed some light to your issue, right?
