Failed load package

Hi,

I work with vs.net 2005, sql server 2005 on windows xp, and until yesterday
everything was fine.

I started a new vb app, and when I tried to add an sqldatasource and
configure it, I got an error about sdk client for informix; I installed that
component for another app but it got nothing to do with this new, so I don't
know what is the problem.

After tried solve that, I decided to uninstall that component but I still
got that error; so I decided to uninstall vs2005 to "clean it", After that I
tried again, and the error was still there, and it was worst because when I
open VS I get a new error about
a "db2vstrt package" that failed. I reinstall it some times, but it's always
the same I don't know what else to do. Any idea?

Thanks,
