Hi all, I have today upgraded Piced & a colour C-Touch to version 4. Nothing else changed in programing, just upgrading Piced & homegate on touchscreen. The screen when downloading the current project came up with error in logic then directed you to the logic Engine. I press OK & it returns to the main theme page. The CTouch then runs normally with no logic functions operating. I have checked & compiled all logic in piced v4 with no problems showing up. Reset colour ctouch to default project, then sent correct project through again. The same error message reappears. Any help :o Cheers Shane
