Lost Gmail-Account since Update to 1.6

Hi there,

couple days ago, I updated my FP1 to version 1.6.

I didn’t really notice immediately, but today it occurred to me: my Gmail-Account is gone.
In other words: no more connection to my Google Play account.

The one I’m looking for now has never been used for anything other than logging into Google Play. So I cannot recover the username right now (using alternative email address or phone number).

Any ideas how to get my account back? And why does this come up now - the last couple of updates, I did not loose my accounts (and I haven’t lost any of the other ones…)

Thanks for your help.

Just to be sure: The Play Store is still installed?

Sadly, if i remember correctly i had to reconfigure my Google Account each time i installed an update.
