Mac thanks for your reply
since you are not experiencing compatibility problems i thought i'd re install muse 2014 and persevere further... So i quickly built a mickey mouse one page site on Muse cc and it loaded on Muse 2014. Tried a 10 page site built on muse cc and it too loaded, but a little slower. Tried with an 80 page site built on muse cc and it loaded on muse 2014 - 5 minutes later! Meantime during the loading process Task Manager was saying Muse not Responding. So they are compatible, i take back what i said.Fortunately once the site is saved as in Muse 2014 it loads normally (doesn't take 5 minutes)
