Flop

Hi, I got an error with v 0.183 (plz check the attached image), I got all filtered roms but when I click to export It says "Please choose the output format from the drop-down menu", and, well, I clicked in all places and typed all possible thins related with output-format and Roms. I´m missing something? Thx in advance. Info: - Windows 10 (x64) - Roms FB Alpha v 0.2.97.39 (Based on Mame 0.178/0.179) - Mame.exe v 0.179 - Tryed to execute lightspeed.exe as administrator and with compatibility in most OS - Last time worked with lightspeed 0.7j but dont know why doesnt work now
