vSphere Web Client: Error #1034 when logging in.

Hello,

Hope someone can help me with this one.

When i try logging in to the vSphere Web Client I get this (Flash-formatted) error box:

An Internal error has occurred - Error #1034

This happens just after successful authentication

I've tried different browsers, upgrading Flash, etc... No luck.

Any ideas? It used to work fine but I don't have a clue what has changed.

Thanks!
