Im trying to create a transport route from KSC to LKO but when i try to connect the computer to the depot while on the launch-pad i get an error saying the vessel is too small. I have tried making larger ones, the the point where they are un-launchable, but i still keep getting the same issue. Have i missed something basic, or is another mod messing it up?

when will this work with universal storage.2? it's the only thing missing from my game..is there something i can change myself?
