After installing MyEclipse 5 with Eclipse 3.2.1, I get an error every time I left-click on an item in the Package Explorer. This independent of the perspective (Java or MyEclipse). It affects both directories and files. The error simply tells me to look at the error log, which I have pasted below. This also seems to prevent me from right-clicking on the project or even double-clicking to open an item.

Sean,
The problem is that you are using incompatible versions of Eclipse and MyEclipse. You actually need to be using our newly released 5.1 version of MyEclipse with that version of Eclipse you have. The fastest way to correct this is to shut down MyEclipse, erase the directory, restart Eclipse using the -clean command line argument. Then shut it down.

Now go to our download section, download the 5.1 installer, and reinstall it. Now fire MyEclipse back up, you should be all set.

(NOTE: Any time you see exceptions like the one you posted, where Methods or Class names are the problem, that is an immediate red flag for “incompatible versions”, meaning that one version of something is looking for a method or class that isn’t in the other version of the program. It’s just a good rule of thumb when troubleshooting these things.)
