The problem of the flight recorder

[Exelion1986]

hello to all
a few days ago, I have finally had a p? of time and I decided to do some logs of my car
not having a power supply for the pc with socket 12v I decided to try to use the function of the flight recorder of the diagnosis
I inserted a sd card and I was able to write the parameters to be recorded on the interface, but only the first time
now it keeps telling me operation failed, I have done several tests of formatting the card, I reinstalled the software and drivers but nothing
to someone ? gi? success?

today I finally managed to solve, after hours of attempts
I really tried everything... I removed the interface, I have reinstalled the software, I formatted all of the possible ways the sd card etc
for a shot of "bottom" at the end I made it, work all the time but I do not think that it should behave this way
however, I must follow this procedure: I create a list of custom data, I try to put it in the flight recorder, disconnects and error, I set the mode? display as a graphic designer and then as a list, the interface will try to reconnect, I in the recorder, and magically it works
tomorrow I try to see on the road if it actually records what must

tried to register and everything is ok, the software will open the sessions, and I view all the recorded data, I see the graphs, the values of the individual points, but...
when I open a session from the interface automatically creates its folders in a file with the extension acfrs that, in theory, should contain the data, or at least I think
c'? also the option to open this type of file but when I try I don't display anything
I tried to open these files with all of the programs in the text and tables that I have but I can only see characters indecipherable and meaningless, doesn't even seem to a list of data in the real world?
I tried to read the sd card using the reader of your pc and tells me it's not ? formatted
so the question of a million dollars (or euros) ?: how the hell are you to export the recorded data on the interface?
I know that it will go? in the end I buy a obd bluetooth and via some stupid software to scan me the log, all of the values that I want to...
