App Not Trusted?

I have recently installed OpenRoads Designer on my machine as a test before installing it on other machines in my department. I have installed standards for my local DOT (Ohio) and everything seems to be correct. All of the DOT apps/VBAs are on my ribbon but when I select one it gives me an error in the message center "<app name> is not trusted" and in more detail, "<app name> could not be loaded because <app name> does not have an authorized digital signature."

In v8i I know one reason this might occur was the MS_SECURITY_LEVEL was set to a high variable but this is not the case here. Does anyone have any insight on this?

Thanks, 

Chris
