I've had 2008 express on this PC since it came out -- I basically have ONE important project that now is being troublesome.

Just had an "unhandled exception" and "configuration system failed" -- errors I've never received before and I've just made minor changes to the program.

For one, I was thinking about a fresh install of 2010 express (but remember some real problems when I upgraded from 2005, so ??) be afraid ? very afraid?

ALSO --

What are the mandatory files I need to save in a project folder?

If I delete the bin and obj folders (plus?) and let it write new ones will that sometimes cure some problems?

What is a good way to SAFELY keep all your hard work but get rid of possible clutter and ?

THANKS.

Configuration system failed to initialize -- what the hell is that?
