Premiere Pro- Crashing?

Adobe Premiere Pro has been crashing on several devices for a class that I'm in.  All Computers are up to date and should be able to support Adobe, and Adobe should be able to support it as well. Internet is working fine and I don't think that is the cause of it's crashing. My only guess could be that it is a server-overload and the crashing is just temporary. But has anyone else been experiencing slow and "lagging" software? I doubt its anything big, but I think its something to look into.
