Hi Lee
I was just talking with my Solid Edge reseller on Fri. We talked about the community edition among other things.
He was saying that it has not really changed but they did "re-do" the interface. It may be worth it to give it a few days and see if you can get used to the new look. I have been running SE for almost 20 years and whenever they change the GUI it pisses me off but I get used to it rather quickly. I say give it a try.
As far as finding the old version, I am not sure if you can still get it , unless you find somebody that has saved it.
I am running the full version.
For what it is worth , I am still running the "ordered" environment, I could never figure out / get comfortable with "Synchronous"
Best of luck
Scott
