It seems that ANOOP was correct. When you create a new campaign, you can name it whatever you want and saving works. I was using a preexisting campaign and was trying to rename it to "Network Campaign" and it wouldn't save it. After changing the name of the campaign, I added resources to the timeline and changed the name of the timeline and it wouldn't save any of the work I had done. I had to go thru a process of elimination to figure out what was causing the system to not allow me to save. It ended up being changing a campaign name. Just thought I would share this info incase others run into the same issue, it could save them some time and frustration and it may be an easy and quick fix on the admin side.
