hello all
can I ask for some help or info for little probem?
Question is: how can I to proceed if I have an old wallet - from 2014?
I mined monero, bought some and then put in cold wallet.
25 word seed didn't exist in that time
The problem is that old wallet can't synx with new blockchain (flashing for sec. and auto-close)....new wallet can't open old files and keys.
bitmonero wallet v0.8.8.4-771b531
Is there way to get accessto  my coins or its just another crypto ....?

Thanks in advance.
