I have been logging and reflashing my ECU without any problems. Yesterday, I was driving and logging with Mitsulogger. Then suddenly Mitsulogger threw some error and I had to close it. Then after restarting Mitsulogger again it did not connect to the ECU anymore. Tried restarting the computer but that did not work. I also have an innovate wideband with usb-to-serial adapter which I was logging at the same time. And Mitsulogger finds and logs WB but can not connect to the ECU. I've also tried EvoScan and it did not work either.
Does anyone know what could be the problem?

 

Some additional information. I've tried uninstalling and reinstalling all the programs and drivers but still no success. EcuFlash also does not connect to the ECU. It finds the cable, but gives an error immediately after starting to connect. Also my ACD lights blink as usual, when the cable is connected.
Anyone had such problem?
