Oh, I must have misunderstood.

"Usually, you need only to synch once with Emplode to cure the problem. If synching once with Emplode doesn't solve the problem, you can force it to rebuild the database as follows:"

I thought I might be able to try synching with USB, then if that failed I'd try going through hyperterminal instructions.

I havn't got the developer version of the player software installed though. Do you know if I'll have any problems installing the developer version while something is wrong with the database?
