I'm having a compile/download error message for any code I attempt to run on my NXT. I've run code on the computers at school that works but for some reason it won't compile on my home computer. I have downloaded the latest driver and tried re-installing it, tried re-installing the bricxcc(both the latest version and the test version from http://bricxcc.sourceforge.net/), tried different computers, tried different NXT bricks. I can communicate with the brick and control it through joystick usb but nothing will compile/download even though it works on the school computers. Here are some screenshots: http://i.imgur.com/gWEbboy.png http://i.imgur.com/QZvJQyB.png http://i.imgur.com/6Ve2YoP.png . If the compiler is set to a different default language other than NXC where would I change it?

edit:
Do you just compile (F5) or compile+download+run (ctrl+F5) or just download (F6) ?
maybe you have stored too many program files on your NXT flash? Did you already erase them all?

I had the same problem. NXT, Bricx 3.3.8.9, Windows 7 64

Solved it by doing the following:
1. Open Preferences
2. Select Compiler tab
3. Select NBC/NXC sub tab
4. Uncheck the 'Use Internal Compiler' check box option
5. Click OK to close dialog

Compile or Compile/Download => Works fine
