Premiere Pro CC Not Responding

Question

Spent an hour with online chat support and lets just say the pace at which the troubleshooting progressed was slower than slow.  My online chat case was 0186030659 for your reference.  It seems I figured out what the issue was in between the dead silence of the chat by doing my own trial and error.  I have an into sequence I create about 3 weeks ago.  Once I imported that sequence my whole project became unstable.  Seems there is some incompatibility with slightly older patched project versions importing into the latest cc.  These types of problems should not occur with a professional editing product and are very unacceptable especially when you spend hours on a timeline only to have it go into a perpetual non-responsive state.  I opened my intro separately and I got a message to covert the project to a newer version.  This conversion prompt should have occurred before importing into my new project and screwing that up.
Anyways the troubleshooting would have gone a lot smoother if the support specialist informed me I could recover from a checkpoint.  As I said, I figured this out on my own in between the dead silence of no follow up from online chat.  A certain amount of lost unrecoverable work is better than nothing I guess...  Really not happy at the moment!

Thanks Kevin.  Your tip is definitely a "word to the wise", but I was a bit frustrated that  in the new CC era where one of the benefits is getting updates, the updates should not create backwards compatibility/stability issues with older projects imported into newer projects (mind you my older project was only 3 weeks old, not months or years).  When I imported my intro project into my existing project I should have received the same message I got when I opened the intro by itself.  That is, "your project was created with an older version... do you want to convert now...".  Adobe should provide this similar warning when importing the project into a new version project.
I recovered my project by reloading my last auto-saved version prior to including the intro project.  I lost probably a couple hours of work but this was the only workaround I came up with.  As I said previously, I had repeatedly asked the support specialist if there was a checkpoint I could recover from and he never responded.  I told him, I suspected the intro sequence, and I wanted to recover prior to the point or try and delete it from my existing project.  I am 4 weeks new to this entire suite of software and I didn't know about the auto-save folder if it were not for my own digging in between lack of response and follow up in live chat.
