Ok, I got them back ! But it didn't worked using your contract adress: 0x8aA33A7899FCC8eA5fBe6A608A109c3893A1B8b2
Instead, I used the old? contract adress : 0x725803315519de78d232265a8f1040f054e70b98 / BETNEW / 18.
Now they appear again in the token list, but they shows 0$ value on etherscan...
At least I can see them, and send them if needed !
Hope this help.
