I can't tell exactly what the problem is from the error message. Can you email the model to
lashkari@worldviz.com so I can take a closer look at it. You don't need to attach any texture files with it, just the wrl file.
On a side note, if you are using 3dsmax we suggest using the OSG exporter available on our download page. It allows you to export models to Vizard's native .osg text format, or .ive binary format. The binary .ive format will load much quicker than vrml.
