When you try to re-run the wallet and it fails, it still stays in systray or task manager. You have to kill the process, then nuke everything except wallet.dat - then update the software and run it ONCE. Each time you close it and try to re-run it, it will fail to open the GUI. Kill the process, nuke all but wallet.dat, run it again. Lather, rinse, repeat - ad nauseum.
Hello Syscoin Team,
wallet 1.2 works for me, but only 1times. If i close the wallet an want to reopen it, nothing happens. All i can do is to kill syscoin-qt over the Task-Manager. OS is Windows 8 x64.
Thank you for some advice.
Same problem here.
Don't close it. You will be fine

It is working now,thank you.
unfortunately it doesnt work for me anymore, no matter what i try. even reinstall doesnt work. i wait for an update.
Same here,again it is not working?
