Very frustrating!!...I have tried upgrading to 'El Capitan'. I have tried uninstalling and installing progs. I have downloaded programs I dont even require.
All I get after all this is 'please sign in' and 'click continue to enjoy software' on a continual loop.
Please tell me someone has had the same problem and managed to sort it out. Ive wasted almost my whole day on this.
thanks in advance
