Zcash4win stuck and doesn't start anymore

[Cereberus]

Whenever I try to launch the client I see the error in the picture below, it is a shame as I have quite a few funds in Zcash there and I don't know how to retrieve  them. Any suggestions what to do ?

It didn't work. I tried deleting zcash.conf and restarting the wallet the same thing. Now I delete Zcashparam folder with verifying key, now it opens and it waits to download the file again, proving key. I have not touched the wallet.dat

Can I install another wallet zcash and import this into that one ? Is this possible ? I hope it is, so any other zcash wallet except zcash4win ?

Look into C:\Users\---USERNAME---\AppData\Roaming\Zcash\chainstate\LOG

You'll see smth. like this:

2017/12/30-22:59:59.000625 770 Recovering log #816
2017/12/30-22:59:59.000672 770 C:\Users\---USERNAME---\AppData\Roaming\Zcash\chainstate/000816.log: dropping 10483520 bytes; Corruption: error in middle of record

In following case delete 000816.log and restart zcash4win
