Cannot assign to read-only variable: ogreMaterial

I get this error message when I first boot 3DS Max 8 (after installing the plugin)

Cannot assign to read-only variable: ogreMaterial

I've seen a couple of posts about the problem in the old threads but I haven't seen a solution. Anything new came up about this issue? Thanks!

The problem rises from interference with another MAX exporter. I guess you can't keep both.

Yup, i encountered exactly the same problem today. I installed the default ogre3d mesh exporter (to xml).. but it wouldn't load.
