I do have the Gallery working on my sites.

I removed the businesscontrollerclass data from the Gallery record in the DesktopModules table as spoken of in this thread

I modified the maintenance.ascx page to replace all references of Gallery_HeaderText with just HeaderText as spoken of in this thread

I downloaded the dll to fix the paging issue. Found at

I set the security on the folder to allow Network Service full control of the DNN folder and all folders beneath it.

And finally, I renamed the original .resources files in the Portals/?portalID?/Gallery to .oldresources and let the module recreate those files. If you have lots of pictures already uploaded then this option might not work for you. You can let the system recreate the files and then copy your data into the file after comparing the files to make sure there is no corruption.

I may have done other things, but I do not remember. If I remember I will edit this post.

Anyway, I hope this helps. I have spent a lot of time trying to get this module working on my own server so that I can role it out to my family. The module has been functioning now for a whole day. I hope it continues.
