At first everything was working. Then I seemed to lose TTZ pro menu. So I logged out and then in. That caused me to lose everything but TTZ and TOTAN. Logged out and back in once more and now I seem to have everything again. Keeping fingers crossed!
I did it this way:
Log into your farsight account and make sure you have TZ and/or STTNG (depending on your KS).
Recover purchases
Log OUT of your farsignt account. Make sure you have your paid for tables, but not TZ/STTNG
Log back into your farsignt account, make sure you have your TZ/STTNG.
Lob OUT of your farsight account. Stay logged out.
Go and tap each of your purchased (i.e., not TZ/STTNG) tables. It should say "Connecting" and then dump you into the table. Exit table and get back to "New Tables".
Repeat for every table you purchased.
Once you have all your tables back in My Tables, log back into your farsight account.
At his point, if you have all the tables, it will say "New tables (none)". And all your purchased and TZ/STTNG tables are together and playable without logging in or out shenanigans.
Edit: The trick is you need to get TPA to redownload all the licenses while you are logged out. Then when you log in, they stay licensed.
