I'm on Mists 5.0.5.

Fresh install of Routes (no existing routes) and only the gathermate2 data (not the gathermate2 addon itself) are enabled.

I went outside the Orgrimmar gates into Durotar zone, then typed /routes in the chat window. The initial Routes panel appeared just fine but when I clicked on "Add," this error appeared:

I thought maybe having the gathermate2 addon (not the data) disabled might be a problem so I enabled it. I got *exactly* the same error as above, but this time the error appeared when I entered WoW on my toon (before, it didn't appear until I tried to add the first route).

I logged out of WoW and disabled the gathermate2 addon (not the data), thinking that I'd go back to the point where the error didn't appear upon login but when I logged into WoW again, this error appeared immediately:

As others have already said, the Routes addon has served me well for a long time. I know you're going through your addons and that you get an email for each comment, and I appreciate you time; especially since you haven't started leveling MoP yet.

I hope this detailed info helps you to narrow down what needs to be fixed. Peace....
