Esteban, I'm running TCM 8.2.6 as well. When I go to software download after selecting a card, I get a grid showing which card I have selected, what is in the slot, and then a couple columns titled NAC/DMF File, SDL File, etc. Double clicking in the NAC/DMF file field, I'm given a Windows Open File dialog box looking in a directory for hd*.dmf (Because I'm on a HiperDSP card, the first two letters might change for Arc/NMC) and from there, I just select the firmware file I want to use. I'm using PRI though, so the .nac file might be because you're using E1's. Not really sure about that. But anyway, that's the process I used to load my DMF files.
