It is my experience that some PC speed up progs have the opposite effect. The alterations that need to made to speed up internet connections vary depending upon the type of connection you have and frequently these programs get it wrong. The only suggestion I can make is to do a system restore to a time before the changes (the prog may have done this for you before it made the changes). If this is not possible, try re-running the program and being specific about the type of internet connection you have. Hope this helps.
