Here's how I resolved the problem: After trying to get all the fixes to work, but getting nothing but errors, I went to Lavasoft folder and re-installed the program from there (they have an installer there), then removed the program again, re-configured my firefox settings (such as open closed tabs when re-opening firefox) and restarted computer. The Lavasoft folder is gone, the error message is gone, so I hope it worked. Lavasoft and it's staff are useless. The only one who deserves some recognition is CeciliaB, for trying to help people... and she's a volunteer. I hope I never have to come here again and I'll be sure to spread the word of this scummy company.
