Convert "Old" BitcoinPRO

[Peace_Maker82]

hello guys

i have a problem with my former wallet.
I have Mining (30.03.2018) with the BTCPclient V1.0.1.0 and have 1253BTCP. Unfortunately I can no longer access them because the client is down and the
address seems to be too old (BJKnAstZUs1gmJzMuaYCUJsUAjPje5) and is not an ERC20 address (https://etherscan.io/) ?
How can I get the Bitcoin Pro back or move them to a new address so that they work again. With working assistance there is 10BTCP as a gift.

Thanks for the feedback......
