Guitar rig and Ableton bug?

[Empiric]

This one makes me feel totaly stupid. I use guitar rig a lot in ableton, the problem i have is if i have exported midi form another software (Reason, guitar pro and pretty much anything) I make a rig, but during the song it loads another preset and the whole song is effed.
Funny thing is the presets are loaded random from the preset folder my created rig was in. It happens at random times and I can' find any automatons that would be doing anything like that.
Does anyone have a similiar trouble?

are you absolutely sure that it is random?

if you program change messages or bank select messages in your midi then it will cause rig to change presets

if you do not know send me one of the midi files and I can inspect it straight up and let you know

Not sure if totaly random, but i know that sometimes the whole song goes without change and sometimes it happens at least 4 times, somitems once and so on. Everytime during another time, it's not like it is changing on 84th bar or so.
I'm at work at the moment, but i'll send you a file as soon as I get home.
