Hey Mackeys,
I'm not sure what exactly you are doing in InDesign, but I had to find some sort of work-around because I don't have time to rebuild my system or rebuild 5 books with over 100 pages of styling and layout - and I'm sure you have deadlines as well... anyway, I EXPORTED the InDesigne Files as IDMLs (note: not the same as SAVING AS IDMLs - which doesn't work). Then I OPENED the files into InDesign CS4 - flowed in all the elements I needed for layout, RESAVED with a new File Name. Then I opened the new CS4 Doc into CS6 and I've been able to work on them... I hope this helps you in some way. THANKS so much for posting this problem in the first place. There is definitely a Bug in CS6 (cloud). I'm going to ask all of my friends that Design Books at One of the Big Companies and see if they are having the same problem because I know they are using CS6. I'm just not sure if they are doing it via the Cloud, which may shed some light.
