Error 000210 that appears in the geoprocesing results pannel is related with different problems:
000210 : Cannot create output
Description The output cannot be created. Potential reasons include data locking, an incorrect path, and limited access rights. Solution Confirm that the data is not locked by another user or application and that you have full rights to the workspace being used. Check to make sure that the path to the data is correct (check for typos in the folder path). Try creating the output in a new location.
But there are some aditional causes:
Error: 000210 Cannot create output when running Python scripts that create feature classes
Check these options...
