version confusion in web download for DCC plugins for Max


I’m currently working on a project using 3ds Max 2011. I can see in the website that the DCC Physx Plugins for 3ds Max 2011 are not available over version 3.2 (3.2.20202.21392). I had a version of the plugin from some time ago downloaded in my hard drive for Max 2011, that shows 3.4.10202.23462 version number. Is there any reason why this version has been removed for 3ds Max 2011? Should I use the one from the web instead this, apparently, more recent one?

I didn’t find the appropiate forum to ask this, and I thought that maybe it was a confusion in the DCC plugin description on the web.

Thanks for your time.
