Hi,

Please ensure that you don't have any non-supported PIDs selected, and also that you don;t have more than 24 channels of data selected. Probably the best thing to check first is:
1) That you have the latest software and firmware (see below knowledgebase articles).
2) Try logging a default PID list ('Duramax LBZ Imperial' for instance) and see if that works. If that does work then it does suggest that you have either too many PIDs, or unsupported PIDs selected.

Knowledgebase articles for software and firmware updates:
- Software
- Firmware

Cheers,
