I have a Raymarine Dragonfly 4 but the serial numbers say CE0168. Is there a manual online? It keeps cutting off on us when we throttle up or down. I am trying to troubleshoot this.

SOURCE: Yes, I just purchased the

Usually when such problems are encountered it is usually as a result of very few things. These are:
- Serials are usually case sensitive
- Mistaking letter O and number zero 0
- Mistaking letter l and number 1
If on the other hand the serial keeps on coming up as invalid then probably the software is not genuine and in this case should be returned to the supplier.
Also you could download a keygen software from the internet and activate your device.
Hope this solution has been helpful?
