plus, even though it is a great add-on program for msn, is not intended for and does not fix msn problems. so whether you installed it or not, it would not help solve your msn problem.
i searched the web and these forums for a possible solution and found that your problem is quite common
without a specific fix...
i found, basically all possible suggestions, on this site:
http://www.askmarvin.ca/forums/index.php?showtopic=199
read it thoroughly.. and see if anything on there helps you out.
you can post again if anything did help so that others may also have a solution
, or if nothing helps, than post again too...
perhaps somebody else on this forum has a better idea of how to solve your problem
Edit: you can also send a message to msn support
