Netbeans done lost it's mind

So I opened NetBeans up for the first time in probably 3-4 days. I haven't performed any updates lately or made any other configuration changes since the last time I'd used NetBeans. But my effort to work on a java app was thwarted by the IDEs inability to find one of the major java libraries my project needed. And what library was that? org.jdesktop.application.SingleFrameApplication! WTF that's the class NetBeans extends when you use the Java single frame application template included in NetBeans. I looked around and saw that the jar file was included and existed on the file-system. I searched around google and came up fairly empty except for seeing a newer NetBeans had been released and decided upgrading would be the solution. Damn I hate taking the windows way out, but that's what happened.
