JSBuilder Error

Maybe this is a bit off topic for the EXTJS Forum, but for some reason I cant get JSBuilder to run correctly on my machine anymore, after doing a .net update.
The error im getting is related to the system.xml object. Unfortunately I cant seem to copy and paste error details, but I was wondering if anyone else was experienceing similar issues.

Cheers,

Adam.

This isn't much to go on since no one else has reported this. If you can't copy and paste the error, can you maybe type it in?? ;) Not sure off the top of my head why this would have broken.
