Please help :)
Thanks
I use the IDE eclipse everyday. Today it decided to not work for me, and I have work to do and really need it to.. If anyone could help, that'd be great.
When I startup eclipse it pops up an error message leading me to this error.

Importing is not the same as compiling. Anyway, you need to associate your project with GWT. Have a look at http://code.google.com/webtoolkit/usingeclipse.html. It might be easier to import the code after creating a new project using this wizard via copy and paste :)
