In reply to NottsRich:
> Lyon Equipment. Mine was certainly more than 3 years old.
Mine was somewhere between 7 and 10 years old. A mate who works for an outdoor retail returned it to Lyon Equipment and they returned a brand spanking new torch.
All above board and legit.
In fact I have spoken to Lyon Equipment in the past about stuff bought from retailers who would not play nicely. Why not call them and state your problem with the XP?
They have very good customer service, and if they can then they will try to help. If they say no, then you've lost nothing.
