My dogecoin QT keeps crashing with 1.5 if thats what you mean.. I simply can no longer use a doge wallet on this pc. I've deleted everything but wallet.dat, it opens, syncs to a certain block then RIP
Are you already updated to the latest, version 1.5.1 ?
BTW, there is now also a "light" wallet that does not need to download the entire blockchain, so it starts fast instead of after a couple hours download (or sync time, depending when you had the QT wallet connected last)
