MobileMail crash after VNSea installed

[2centplain]

I had MobileMail 1.1.1 working fine.
Then, I installed VNSea. It crashed once, then worked OK.
Now, MobileMail is crashing. (Other applications are fine.)
I've reset file permissions (755).
I've reinstalled MobileMail.
I've resintalled the Framework stuff.
No luck.

Ideas?
