I looked through these discussions and found a number of posts related to running in medium trust and it sounded like medium trust support was added in earlier versions.  My host only supports medium trust and when I attempt to load the module, I am getting the following error. (latest version of nb-store)  am running dnn version 4.9.5

Is this a trust issue on install?

That looks like a permissions issue to me. Try re-applying the correct DNN permissions for Network_Service to the file system and let's see what happens.
