Import Error:  Cannot import name  ExportTileCache

Discussion created by ahos77 on Nov 1, 2012
I installed the 10.1 sp1 the other day and my scripts stopped working.  The following is what is showing up:

Traceback (most recent call last):
  File "c:\location\script.py", line 10, in <module>
    import arcpy
  File "d:\arcgis\desktop10.1\arcpy\arcpy\__init__.py", line 24, in <module>
    from arcpy.toolbox import *
  File "d:\arcgis\desktop10.1\arcpy\arcpy\toolbox.py", line 485, in <module>
    from management import ExportTileCache as ExportTileCache_management
ImportError: cannot import name ExportTileCache

When i look at these scripts with the debugger, including arcpy.management, they are either not there or not linked, i.e. have no information associated to them.
I have downloaded the sp1 for 10.1 desktop twice and installed several times with no change.
Any help would be greatly appreciated.

Thank you
