So I updated my wallet from v0.8.6.2.4-g000002-beta to v0.8.6.3-beta. The new wallet syncs without problem but it shows 0 coins. Why?
When opening the old wallet all my coins are still there.
The folder where the wallet.dat file changed name.
It as "Karmacoin" (C:\Users\YourUserName\Appdata\Roaming\Karmacoin).
Now it is "Karma" (C:\Users\YourUserName\Appdata\Roaming\Karma).
Backup your wallet with your old wallet (tho one that shows the coins).
Place the file with the old wallet (name should be "wallet.dat") inside the "Karma" folder, and start the new wallet.
After synchronization with the network all your coins will be in your new wallet.
Good luck!
Download the newest wallet v0.8.6.5. it should download on /roaming/karma
copy the karma-qt.exe
Paste it in the old folder.
Rename it to karmacoin-qt.exe
run the wallet
if it doesn't start synching in few mins then hover over with your mouse and then click help - debug window - console
copy pasta these two nodes one by one and close the window
addnode altcoin.dk:9432 add
addnode altcoin.dk:9436 add
wait a few minutes. up to 20 mins
after full synch you can then send your coins to the new address

go to destination folder of the new wallet. should be /roaming/karma
pasta and overwrite the "wallet.dat" of /roaming/karma with the old wallet.dat of /roaming/karmacoin ( make sure your have no coin in the new wallet because this will delete this wallet data)
run the wallet
if it doesn't start synching in few mins then hover over with your mouse and then click help - debug window - console
copy pasta these two nodes one by one and close the window
