Will do, I'll call them today.

I have a Pentax dedicated Promaster 7500EDF Digital flash.
It works flawlessly on my older Pentax DSLR but it only fires at full power on my new Pentax K-01. After some testing with other dedicated P-TTL flashes, and online investigation I found that the camera is working correctly. I assume Pentax has changed/updated their communications protocol between camera and flash. Is the firmware on the flash updatable? Has Promaster released a firmware update to address this issue? If so how would I send in my flash to be updated?
Thanks in advance,
