DHP software does not work with HPT hardware, so you would need to buy a DHP tuner to wap the file.... But you still lose the 2 credits you unlocked on the 01 file.

You really need to see if you can open the 01 file you have in Tiny Tuner.... Its the cheapest and best plan of attack at the moment as you can possibly keep your 2 credits. If you cant get TT to open the file right off, there are ways to make it open it and disable the cat part... ways that are probably worth investigating.
