So since some time in Atmel Studio 7 my code completion stopped working. Also it does not recognize the registers anymore. This is also the case for codes i wrote when it still worked. When going back to these codes it is also gone. I am still rather a noob in using atmel studio but i think it is intellisense which stopped working. I already tried multiple aproaches like reinstalling the whole of Atmel Studio but nothing worked. Does anybody have any idea what could be the problem?
