Problem with some tracks and original GP4.exe without use GPxPatch (2 replies)

I faced a problem using some tracks and original GP4.exe without use GPxPatch.

Usually I use GPxPatch to start GP4 without any problem with all my tracks, but recently
I made a GP4 customization that allow me to run GP4 in SBS mode using vorpX+SplashTop and display
a 3d vision of GP4 on my smartphone inserted on a Homido headset (a very funny solution!)

vorpX is a tool that creates a SBS vision of GP4 but it is incompatible with GPxPatch so I was forced to use the
original GP4.exe without GPxPatch support.

Many tracks, expecially the original ones, run fine with original GP4.exe, some others crash GP4, an example of this situation is the
Urbano Ficticio track (http://www.gp4central.com/tracks/).

Can someone give me a suggestion to allow me to use all the available GP4 track with original GP4.exe ?

Thanks in advance.
