I accidentally entered the password un correctly 2 to 3 times and this message keeps popping up "already logged in or server is under inspection" when i typed my password correctly. Please help.
It sounds like you're stuck, although I've never heard of it happening this way, personally. Try again every couple of hours, and if you don't unstick naturally, the next server check will fix it.
Tried to login again but it didn't work. Any idea when the next server check is going to take place? >_<
No idea, sorry. They're announced several hours ahead of time in Administration, Development & Support > Announcements.
