Anybody else having problems with nexus-qt? it won't open for some reason (win10)
Has the wallet already been synced before, or did you try to open it for a first time?
Did you wait long enough for it to open? Sometimes it can take 5-10 or even 20 mins to load (it depends on your computer).
The wallet eats a lot of RAM memory (over 1GB), so maybe you didn't have enough free memory at the moment?
