Help After 2.2.1 email crashes

[eMonkey]

Hi,

After putting the 2.2.1 upgrade on via Kies my Email crashes on startup.
I have just one email account which uses IMAP.

I'm new to android so wondering if anyone else has same problem and knows how to fix?

OR ... what do you do when one app crashes on startup? Is there some way to reinstall or reinitialize just that app? ... esp. when it is email.

Help much appreciated.

Richard
