Hey guys, excuse the new account status, but i couldn't get access to my old BTCtalk one.

Anyway, I was looking through some REALLY old backups, and found an old wallet file from 2014 with some C2 in it! I never knew i still had some, so i didn't keep up with C2 developments, but i see the coin is now called "C2.1". Was there a fork or migration or... ?
I can see using the old wallet that i have some coins, but the old QT does not connect obviously. I have tried to use my old C2 wallet.dat with the current C2.1 QT version, but it does not accept it. Any info on how i can access my C2, so that i can have some fun with trading?
Many thanks!
