What would make my Cp7 course get hung up during the loading process when launching on LMS?

Question

In Cp7, I created a SCORM project to post on our LMS and submitted it for testing. Our LMS department confirmed it worked successfully, and in fact I tested it myself – it worked great. However, my work team asked me to make some changes to the content before pushing it out of the testing phase to launch company-wide. Per company policy, making changes to a course means resubmitting it once more to be tested before making it available to everybody. So I made the requested changes and resubmitted it for testing. Now our LMS department reports the course will not launch properly – it gets stuck in the loading process. It shows “Loading...” endlessly but never loads.
When I submitted the updated version for testing, I kept all the project settings that worked successfully the first time. The changes I made to the project were:
I added a slide toward the beginning (slide 2) to give the user navigation tips.
I set slides so that each one must play all the way through before the user can proceed to the next slide (I think I did this simply by removing “play” on the playbar”).
Under table of contents settings, I checked “navigate visited slides only,” so the user can navigate backwards using the contents bar at left, but can only navigate forward to slides that have already played or to the next slide in the queue.
I broke up a couple of lengthy multiple choice questions into shorter ones (for an additional two slides).
Is there any reason one of these changes would make the course get hung up during loading?
Is there a size limit Cp7 projects which, if exceeded, might be causing such an issue? 
Or does anyone have ideas about what else might be making it get hung up in the loading process?
Thank you, any and all, for your feedback.

back up the iPhoto library like any other backup - make a copy of the iPhoto library in case of problems
you Depress the option (alt) and command keys and launch iPhoto - anyplace you can launch iPhoto you do this - keep the keys down until you get the rebuild window
