method in your Forum class never closes. It starts with "/*" so just change that to "//" and you should be all set if that's causing problems..

4,254 PointsBased on the error you're getting. That should be the solution.. Maybe try closing out of workspaces and coming back to it. Also look for anymore open comments that arent closed..
