Still the same problem. > Might it be python 2.6? I notice that, in general, python is not backward compatible - a major design error IMO. Its also quite easy (too easy?) to write non-portable code. In addition there is more than one flavour of Python for Windows which may or may not be compatible. I wouldn't know: I've only looked at Python for Linux and have backed off that once I realised that a 2.6 program isn't guaranteed to run under 2.7 or 3.2 - a disappointment, as apart from that, it seems quite a good language. Have you talked to the authors to see what version of Python they used to write Calibre? What flavour of Python have you installed - Linux or Windows? Martin
