Saving the lineup under a name not used by the program to save lineups solves this issue for me. I can reload my last 'winning' lineup this way. Also, be sure to hit the 'load all eligible cards' option before doing this to get your best guys ready to go.

I've found that this issue arises when the PT servers are at their busiest, usually on the weekends, around the time the games are simulated.
