LFS throws to Windows desktop

[WyX]

Sorry, I didn't saw that edit#2. I was writing and doing other things at same time so my "writing session" propably were over 10 minutes. =) I will try that one by running TC Lights as an administrator.

And like Barney said it might be better to try to find the problem itself. I'm going to look tasks etc. and shut down the useless ones. Also I'm going to do a pure cleaning - uninstalling all useless programs, run different antivirus and cleaning programs etc.

TC Lights isn't the reason, I had same problem before ever used TC Lights.
