Ok guys, I'm really sorry to be a bother or sound like an idiot. But here's my issue.

I downloaded the KeyID wallet.
I switched to the legacy ui
Imported my PTS wallet
Got my shares
Went to freekeyid.com
I tried with both google & twitter
put in my long address
put in what I want my name to be

I keep getting this: invalid transaction expiration (31011)

Then, I tried registering within the legacy ui in the wallet, and got the same thing.

THEN, I couldn't figure out how to switch back to the new ui, to try and start all over again.

I closed the wallet/reopened, and now I have it back at square one. A key, and no way to register/authenticate it.

I'm on a mac. I'm a mess. If anyone could maybe lend a hand I'd really appreciate it. I searched the forum before posting this, hoping it was a common thing, but didn't see anything like it.
