I'll post what I posted in IRC, but no-one responded. >_>

<Matthew> Hello, I have a problem with Messenger Plus.
<Matthew> I got a computer virus a few days ago, it uninstalled most of my programs. I removed the virus and reinstalled my programs, including MSN and Messenger Plus. 
<Matthew> However, everytime I shut down my computer since then, Messenger Plus has uninstalled itself. I had to keep reinstalling it everytime I want to use it.
<Matthew> Now however, Messenger Plus installs, but when I open messenger it doesn't appear, AT ALL.

Anyone know how to fix this?

Thanks
