where did my menu bar go?

After opening the progam and looking at it for a minute (only to see that it could only access the discoverer page - useless), my menu bar just disappeared! My mac acted slow and I wasnt sure what to do. After I restarted it the menu bar was back without the Instabar app in it… I dont know what happened but I deleted Instabar after.
