Not sure if this is the correct area for this post, so apologize if it needs to be moved...

I recently purchased a tune from a Company here in the UK where I'm based.

They sent me an AlienTech Powergate3+

Type: User
Vehicles: Car

HW: 06.43
FW: 02.09

I was to use it on my 2011 Audi TTS. When I received it, I read the ecu from my car, used the Powergate3+ User software to download the stock file to my computer, send it to them, get a tuned file back, upload it to the Powergate3+, then flash to my car. This turned my car into an un-drivable mess with countless problems. I contact them the next day, and got ignored. I then spent 3 weeks chasing them by email, phone, facebook etc and got nothing. During those 3 weeks I re-flashed the stock map (which fixed everything and put it back to how it was - at least, it feels the same as before), used "Erase Data" in the software to remove the tuning maps from the device and I then raised a dispute with my card provider for a charge back since they weren't responding to my help or return requests.

They've now come back to me offering help - but now they're saying that by me erasing the maps from the device it has reset the entire unit since I can no longer read a new stock file, nor can I upload any tune map files (It give error of ERR_INVALID_FILE). I also can't erase data again as it gives a warning about no credits. If I connect to car to read new stock file it says mod files (I think) empty and I need to contact the master!!

If this normal? Surely a device that's sold to me as being able to store 5 maps and be used to reflash whatever I want anytime, *SURELY* erasing my map files off the device wouldn't cause these problems!?? What the hell has happened to it!? Is there any way I can decode or revive stuff my end?
