Little background.  I'm a systems engineer that works on Windows boxes for a living, IIS, DC's, SMS, MOM, lots of vbs scripting, some realy basic .NET experience making console and simple win32 applications.

Ok so I'm only partialy proficient in doing this dotnetnuke stuff and have a hosted solution that was preinstalled for me that's core version  DotNetNuke 4.02.

I mistakenly(think it was a mistake?) installed the most up to date version of the forums module and when I go to the "Manage Forum Users" area to grant moderator priveledges and such everything crashes.  Based on the error message I'm thinking my newest forums module is making calls not present in my older core version of DNN?

How the heck do I fix this?  Remove newest forums version and install older?  What version of forums matches my core version?  Install newer core version?  Don't want to put my site in an unusable state that will take me hundreds of hours to reinstall myself :(

Documentation is sketchy beyond basic user UI stuff that I easily figured out on my own.

Thanks,

PFD

Forums 3.20.01 matches DNN 4.0.2.

I delted the newer 3.20.08 forums I had installed and lost all my postings and reinstalled the older version and it's 100% functional now.

I did check out the referenced forums and liked it and would have used it but it too gave me crashes.  It also must have a level of dependancies newer then 4.0.2 has support for.

Looks like I need to figure out how to upgrade my core version.  Any suggestions for instructions that actualy make sense from step one through stpe whatever?  Instructions for high level checklist items that need to be performed? 

The way information is organized(or not) reminds me of the linux community.  DNN needs some more sticky FAQs for basic stuff at a level of detail better then clicking through the interface.
