Like @AshuraDX stated, I have not had time to recompile the dotXSI exporter for newer versions of 3ds Max. My recommendation would be to export your animation into a format that is supported by the legacy Softimage XSI ModTool (v6.0 or v7.5) application... like FBX, and then import the FBX into ModTool and re-export as dotXSI 3.0 from ModTool. This will allow you to keep your current workflow process and avoid Blender.
