I have moved your post to the Carbonite section of the forums.
Since you mention an update from yesterday, I assume you are using the beta version and not the tried-and-tested release version? (It's always good to mention these things so no one has to assume what version you have.) Since the beta version is for 5.2, it has a TOC number of 50200. The current WoW client looks for a TOC number of 50100 (for 5.1). Since yours doesn't match, it's marked as "Out of Date". Did you check "Load Out Of Date AddOns" in your addon menu at the character select screen?
Or is it that Carbonite *is* loading but is giving you errors? (Make sure Lua errors aren't hidden in your Interface Options.) In this case, what errors are you getting.
For future reference, when reporting a bug, this is the pertinent information to give:
1. the version of the addon
2. the version of WoW you are trying it with
3. any errors you are getting - and/or - any other detailed and precise information on what is happening
As an extra note, please refrain from using more than three exclamation points in your post.
