Tactice Trainier playing tricks??

I use the Tactics Trainer quite a lot lately and I've come across some broken pgns that I obviously couldn't solve, but still my rating was decreased. How can I solve a broken problem (a message that states the problem with the pgn actually appears in the top right)?
I had a Tactics Training session last night which ended at 10pm and when I started my morning session I noticed that the Trainier has charged me dearly for two skipped problems at 9:30pm. Very starane. I do not remeber skipping any problems.
