File becomes corrupted after inserting a .mov file

Hi Becca thanks for reaching out - we opened a case immediately, sadly they were not really able to salvage much of anything. bottom line - the .mov file corrupted our storyline file.  (Not sure if it was a.mov, or an animation codec, or the overall size of the file which, unbeknownst to us was 2.5GB- a short 30 second file straight export from after effects - (a miscommunication on multiple parties and the wrong file was grabbed and inserted)  All of the above probably contributed - But Storyline should not have let us insert the file in there first place or there should have been a warning.  I post because I am certain there are other out there who may also be experiencing a corrupt story file and don't know why.  

Here is what is odd - Working on the computer desktop: We created the project file - inserted the .mov file and published the project - the project sits on the Articulate Review site now - We received comments and made updates to the course - made the revisions but wanted to let it sit - so we closed the course.  Upon attempting to reopen the course - we receive an error message saying the file is corrupt or created with an earlier version of Articulate.  Earlier version is NOT possible - but sure we are game to try to back up a version if it means opening up the file - no luck - we even tried updating to a later version incase a newer version would open it - no luck.  We did however have an older version of the story project file (one without the video file inserted - although at this point we did not know that was the culprit) and it was opening up...so at least we were NOT beginning from scratch.  And then - bam - soon that file was corrupt too...We thought it was possible Dropbox was corrupting the file as it seems to be after we would post a copy to dropbox that it seems to go bad - but that was circumstantial.  That is when we realized the connect between the story file corrupting and the insertion of the video file (which is NOT corrupt - just large and specific codec - that file type and size clearly does not play nice with Storyline.  

A long tale to hopefully help others against inserting larger quicktime.mov files in their Storyline projects and reflect - if they do have a corrupt file to consider - did I insert a .mov file in my story project file?  if so - that might be why.  and finally to alert the awesome staff at Articulate of this potential problem and see if there is some way they could insert a prevention or warning against inserting large video files or files of certain compression types.   You folks are tremendous!  And we appreciate all the support you give us!
