any ideas?

Not really, you need to tell me more. How are you running it - what command? How did you install the script, is the file somehow corrupt or has it been modified?

Code:

File "E:\Python27\texturecache.py". line 1418
  data.append({u"textureid": r[0], u"cachedurl": r[1],
                          ^
SyntaxError: invalid syntax

The code path you are having a problem with I have tested on Windows 7x64 with Python 2.7.3 and Python 3.3.1, and there is no syntax error. You could try removing the unicode type prefix (u) before each key, that's superfluous and could in theory be causing a problem if your Python interpreter doesn't support unicode but that doesn't seem likely with Python 2.7.6 and I also don't see why it should be a problem only for you.
