First of all, CA provide two cs2_exporter.dle, one for 3ds max 2010 32 bits and one for 3ds max 2010 64 bits version.
Same for 3ds max 2009.
So, make sure you use the right cs2_exporter.dle file.
Second, be careful with models provided by CA. You cannot open them with 3ds max 2010 as they have been create/save using a newer version.
Open them with 3ds max 2012 or 2013 and save them as .max for 3ds max 2010.
Then, you will be able to open the model with 3ds max 2010 (*)
Note that I have to run 3ds max 2010 as administrator to open the model.
Then, go to 3ds max menu > EXPORT > EXPORT > choose CS2 Max Exporter
If you didn't have the "
CS2 Max Exporter" option, you will not be able to export your work to cs2 file format and then create files for the game using BoB.
