Urgent - No portal desktop defined

Hi there

I added my portal desktop to a transport package in DEV, then imported that package into the QA portal.

I then located the master rules collection, and changed the settings such that all users would use the desktop that had just been uploaded.

I then logged off, and logged in, only to get an error message saying "No portal desktop is defined for this user ...".

What do I do now, as I can't log in to the portal to change things. I have tried logging in as the J2EE_ADMIN user, but get the same error message. Is there a way I can edit the master rules collection from elsewhere?

Please, this seems like a bit of a trainsmash to me 😔

Cheers,

Andrew
