Hi Drew,
Please note that the current Genos firmware is V2.10. If you have only updated to V2.02 now, please also update to V2.10.
When saving the Pack Install file, please make sure that ".cpi" is set as the file type. If ".cqi" (Pack Quick Install file) is set, click on it and select ".cpi" instead. This file type is required to perform a full pack installation.
P.S.
Regarding deleted data in your User drive: It is possible that the deleted data in the User drive could be restored from the computer in USB storage mode. I can't recommend a suitable program for this at the moment, but there are data recovery programs (some free) that can restore accidentally formatted drives. If you want to try this, you shouldn't save any new data in the User drive at this time (and don't install any Expansion Packs either, because the folder "Expansion", in which the styles, registration files and multi-pad files of the Packs are stored, is in the User drive).
Best regards,
Chris
