Hi Stefan,
The file yo try to open seems to be directly extracted from Studio file. But this one does contain two files, one is a regular LDraw file with normal LDraw colors (model.ldr), the other contains embedded parts and use BL colors (model2.ldr). Why not use the first one?
Otherwise it should be possible to write a LDCad script to convert BL colors to Ldraw ones...
