Hi,
win 8.1 QT Version 5.2.0
win 7 won't open wallet ,
Devcoin-Qt (OSS GUI client for Devcoin)
Devcoin-1.0.16-w32\Devcoin-qt.exe"
Can't work out how to insert screen print
hopefully this helps
Why don't you save your wallet.dat and upgrade to newer version of Windows? Windows 10 working fine. It was a free upgrade for me back in 2015? I think it was 2015
