Dang. Well, worse case scenario, you'll have to address it on F2P launch.
PTR in it's current iteration should be available to everyone. You won't be able to access PTR without signature/credd once drop 6 goes live.
Your addon is apparently conflicting with the new control settings for mouse control that Carbine added to Wildstar on the PTR, may wanna look in to it before it reaches live. The addon completely stops working altogether.
