Rct 2 help

I downloaded the tranier (sp?) for rct 2 (i know im way behind on the times) and im having. a little trouble. Whenever i take a ride and change track, train, or operating type through the trainer
(sp?) it drops the rides reliablity from 99% to 6%. Is there
Any way to prevent this. Oh an once this happens as a result the rides break down every 5 seconds.

I recall a "make rides reliable" option in the trainer, which will take care of the problem.

I alwys select it and it dosn't really help. I find it won't do it if i change lift speeds but if i change anytrhing else on a ride than it will.

That Happens to me to all I do is close the trainer then reopen it and it works
