Hi everyone, Hope someone can help me out here. On Friday I downloaded a program called "alltoavi" as I was trying to convert a .mkv file to .avi. The website I got it from has been around a long time and I've never had virus problems from them before. Here it is: http://www.videohelp.com/tools?convert=MKV to AVI Anyways, I installed the program on my computer but it wouldn't open. I figured because that computer was running off Windows98. So I uninstalled it and since then I've had nothing but problems. None of the programs will open, Microsoft Outlook, Internet Explorer, Adobe, along with just about everything else. I just get a error message saying it was unable to locate the "______.dll" file. Any ideas how I can repair this?
