Sounds like a problem in the driver, it can't find a constant by the looks of it. Make sure you are using the latest version, and otherwise report a bug. As a side note: 1.5.3 is rather old (even for the 1.5.x series itself), you really should consider upgrading (preferably to 2.5, but otherwise at least to 1.5.6). Mark
