Is this a memory issue? I just downloaded a program (Flash Decompiler) and it won't open. I've double clicked the icon, the little hour glass does it's thing, then nothing. I tried rebooting my machine, and then it worked! But after I messed something up with it, I had to close it. When I tried to open it again, it wouldn't open.

I've rebooted 3 times since then, and it still won't open.

Edit: I use Windows XP Home Edition.

Edit edit: And I just noticed that my CPU Usage is at 100%. I only have IE, AIM and msn messenger running. @_@
