MX Simulator

Just got the game a few days ago and it seems that most tracks won't show decals or textures. With the Stewart Compound I only seem to get a white texture and Pala just shows as the stock texture with no roost, the same goes for Mission Valley. The only tracks that I have downloaded and have worked so far are Redbud 2010 and the Supercross tracks. The error I'm getting is Warning: Missing shape file @Pala2010/roundbale.shp. I have the feeling that there are more errors, but I just can't see them.

I would try to get a screenshot but the in game screenshot won't work and I'm running bootcamp on a Mac so the software screenshot is a no go.
Anybody have any suggestions?

Same any track with a sand texutre on it Pala Raceway, Black Mesa MX come to mind its anoying as everyone goes on about these tracks and i can't play them properly or see them. it would be great if some can help.
