If you do not have the tokens, then please provide us with the UDID information. We may be able to match information from your prior registration of the devices.
Apple have removed access for developers to UDID information, which we previously used to positively identify/match registrations. We now use our own 'TPC Device ID' based on software identifiers that Apple permit us to use. However, the identifiers can change depending on how devices are installed. i.e. if you install TPControl on the device using a different Apple ID, the identifier changes. If you reset the device to factory and do not restore from a backup of it, then the identifier changes.
