Okay, so I finally got back to drawing, as you can tell from the very frequent updates. Unfortunately, it's difficult to do anything digitally artistic when every bit of computer art software is getting constantly and infuriatingly blocked by your anti-virus software.

Thus, we see the problem. McAfee seems to have not only blocked Photoshop from my computer, but actually removed/shredded it. I don't know how, it shouldn't be allowed to do that unless I tell it to, but it's not in quarantine so I have to take it that the AMTLIB.DLL file has been completely expunged from my computer. This, naturally, is very irritating. I'm currently trying to work on ways I can get it back. If nothing else, I know for a fact I can get a full software restoration from a friend of mine, but it's still going to be frustrating having to white-list several dozen sub-files again.

Still, now that the process has been learned, with luck I should be back up and running within a few days, two weeks at most. Sadly there won't be any updates until this matter is resolved, for obvious reason.
Let's hope it gets fixed soon.
