		pid = pid[0:-2]

Does it work for you?

If the decrypted result is garbage then your PID is not correct.

When I try this, inputting the shortened 8 digit PID, it tells me the correct PID is the 10 digit 'abc123...' - which is exactly what it rejected in the first place!
It then gives me 'invalid PID checksum' and does not convert.

I'm using v0.4 of MobideDRM and the PID is for a Windows PC running XP.

Does anyone have any other ideas, please?

Thanks
