I was that soldier! Only one post to the thread and no response until now. (You should have simply replied in the original thread instead of starting another one!)Suggest you mark the other one as resolved and continue with this one.
Go to Start>Run and type "msconfig" in the box. Go to the Start Tab and look down the list for anything connected with Messenger or Net framework and untick them one at a time. Exit and reboot on each occasion. If the message re-appears go back and retick the box and try it with the next one.
We could do with the exact message posted here including what is in the title bar.
