This is a CM V0070 related issue. You can continue this quest with the original version, with CM V0064 or with the coming patch. The quest will continue normally, it just don't get pass this one step in CM V0070.
As I mentioned before, problem is found and already solved in Version 0072 (only accessible for the testcrew) and will be gone in the next version of the cm-patch.
