I can't log in in my skype. Login and password are correct. but system snawer me "could not load the Skype database. maybe it used by different working copy. exit from Skype and enter again". I've done this million times but it doesn't function. I've changed password, but it doesn't help too. at the same time my sister doesn't have any problems to log in her skype from my computer. Please explain me what's a problem!
