That's it... I upgraded from 1.1.0 Final to 1.1.2. All went fine, no errors, MP working right... BUT, I got an error when entering MP plugin config, or when closing MP config, about nlog.dll not found... I've just placed nlog.dll from my 1.1.0 Final backup in current MP installation dir , and it's working again...

bye!
