login question

when I try and login on the computer at work it says "can not proseed" what the hell am I doing wrong? do I need to logout at home? Thanks Greg

 

I do NOT claim to be computer savy but I would "log out" at home..........before I tried to log on at work.

That's what I have to do


Then log off at work BEFORE you go home.
It is my understanding rhat only 1 login is OK at a time.
