Why drag to place failed in routings?

Hello,

I often meet this error "Drag to place failed" in Solidworks routing. But when i try to reappeared this problem, it disappeared.

Error description:

  1. i drag into 5 connector (3pin) female.sldprt file from the routing library into assembly and save the assembly to disk D:.
  2. Then i try to drag into another connector (3pin) female.sldprt, it appears the error "Drag to place failed".

My guess:

  • The first 5 connector (3pin) female.sldprt are from the routing library, and were saved to disk D: they are now located in disk D:;
  • The another connector (3pin) female.sldprt is from  routing library of disk C:,
  • The part are same and with same file name, but from two different place, it will has this error.

Am i right, how can i resolve this error?
