If you are still having trouble try posting a question in one of the tech forums online. There are many of them so you may want to post the question at several and check back for the answer. Usually if I have a problem I can't figure out that is a tech issue, I can find an answer at those forums.
Also, if you haven't already, try going to microsoft update just in case the version you just reinstalled doesn't have the updates that have been released since you got it.
