Problem with SM64 editor 2.0.7

Hello, i have a problem when i try to import an obj file with Super Mario 64 editor 2.0.7:

when i select the model i get an error message that says: "exception not handled by the application, click continue to ignore the error and attempt to go on

"126000090" is not a valid value for 'red'. 'red' must be bigger or equal to 0 and minor or equal to 255'

this problem affects also the fact i cannot edit the collision neither select the textures in thed importer

Anyone knows what is the issue?
Thanks in advance

Are you a french guys ? if the answer is yes try to turn your computer's language to English that fix the problem ;)

What ? my comment isn't rude :/ this problem with the editor is specific to french poeple, I just try to help him with the solution that I know, where is the problem, I don't understand :/

I was attempting to import al level and i realized that some of my level geometry was white eventhough i had textured it

When i touched that specific geometry in game i would fall through it sometimes get stuck inside of it. And the texture doesnt seem to be the problem because the same texture worked just fine on the spot byhind it. This is a link to the imageof the glitch
