Can you open a .PCE file?
EDITED BY MODERATOR: Moved to the Import/Export space. Please post to the appropriate space when one exists.
What application is your "PCE" file from?
I couldn't get a definite hit on the ether.
Also, drop File>Open and review the extensions listed. If you don't see PCE, then you'll most likely need to save the PCE into some intermediate format that SW can open.
