Import Arcpy error

[DanielHall_Ballester]

Hi everyone,
I've searched the forums and the internet for an answer to this, but unfortunately I've had no luck.
I'm running Arc 10.1 sp1

Regardless of whether I use Idle, pythonwin, pyscripter or the built in python editor window in Arc, I get the following error when I try to import arcpy

>>> import arcpy
Runtime error
Traceback (most recent call last):

ImportError: cannot import name datetime_data

The python installation is not a standalone one, it is the one installed when installing Arc,
so in the python27 folder within the C drive, there is only 1 folder, this is ArcGIS10.1.

Therefore I am unable to carry out the fix provided by Kimo in post #2 here

I've also looked at the contents of the Desktop10.1.pth file and the file paths seem correct ( as specified in the Tip at the bottom of this page http://resources.arcgis.com/en/help/main/10.1/index.html#//002z00000008000000 )

I have 3 lines in this file, as below:
C:\Program Files (x86)\ArcGIS\Desktop10.1\bin
C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy
C:\Program Files (x86)\ArcGIS\Desktop10.1\ArcToolbox\Scripts

Any ideas what I can do next to try and get arcpy to be recognised?

Many thanks

Dan

It seems to be finding and working with parts of the arcpy site package.
It is just encountering a hitch in the git-along.
(ImportError: cannot import name datetime_data)

If removeing and reinstalling the python provided with arc does not fix it,
it sounds like a Support Call is in order....
