Creative Cloud update to 1.8.0.447 overloads Mac CPU

Yesterday morning I was prompted to update Creative Cloud to version 1.8.0.447. This is on a MacBook Pro running OS X 10.9.4. Almost immediately after the update, the fans on my machine started running full blast. Checking Activity Monitor showed that the %CPU value for Creative Cloud was 100% plus. I couldn't find any way to quit Creative Cloud, so I killed its process with Activity Monitor. Every restart since then has required the same steps. I read some advice online that suggested logging out of Creative Cloud and then back in, but the log out option in CC's preferences is inactive. From what i have read, this sounds like an old bug that was fixed a few versions ago, and now has resurfaced with this latest version.
