error with save uv layout SOLVED

After watching the LSCM UV mapping tutorial I decided to try some things. I first unwraped a cube and saved the face layout no problems. However when I made a more complicated object I recieve an scrypt error when useing the Save uv face layout scrypt.

File “<string>” line 132
Indexerror: list index out of range.

Been searching this forum but could not find any relation to this scrypt with that error.

{EDIT}
Sorry folks, it seems I have solved the problem, it seems I was trying to save the uv layout while I was in face select mode. When I leave face select mode I can save no problem.

Decided to leave this post instead of deleting in case someone else has this problem too{/EDIT}
