I have a problem, at download the block, there is a message: runtime error this application has requested the runtime to terminate
Please help. Thanks
Anytime something like that happens for me, I first try the simplest fix and uninstall and then reinstall the program.
Perhaps try going to your AppData (I'm a Mac user so I'm not exactly sure what folder it is in Windows) folder to find the XCurrency folder and delete everything but your wallet.dat and then reinstall the wallet and see if anything changes.
