So what does your meid say now, is it still the same as it was before?
The meid is written multiple places in the ram, so were you in debug mode messing around with the meid or did it just happen?

Sounds like you need them to "reprovision your phone" (call them on a different phone) and also run the "update" on your phone again if your data isn't working.

It needs to download the hdr username/password again (this is derived from your meid, so if you have a NEW meid, sometimes it will not want to download the correct user/password for some reason, even if the new meid matches the meid on your account.)
