"WHATEVER THEY DID TO IT KILLED IT!!!"
I have used it for years with few problems.
My current program apparently became corrupted. I downloaded the new version and it screwed up the computer. I couldn't get on the Internet or much anything else. After numerous attempts to try to figure out why it was happening, and correct it, I was forced to remove it. After that everything seemed to be fine.
Well, it used to be a decent program but obviously they have done something to it that makes it pretty much unusable. By the way, I'm running Windows 7 and use Firefox.
