Error message - Project spec must start with $/

While trying to convert an old VSS repo (I export the entire $/), I get this 
error message:

---------------------------
Error
---------------------------
Project spec must start with $/

Parameter name: projectSpec
See log file for more information.
---------------------------
Abort   Retry   Ignore

This is the relevant part of the log:
