Hi I am building a USB MIDI controller and have nearly finished my project when suddenly my Leonardo has stopped uploading. This is very frustrating considering the time I took for this project and changing the board would be a real problem.
The board is recognised and still transmitting on serial port when I connect it, with potentiometers and button working fine (only my trellis LEDs turn on in a weird way when I turn the controller on) but I can no longer upload any sketch.
I have pasted the error message:

I have disconnected all midi programs that could interfere with with the Leonardo (midi Ox, bome midi translator, previously the have interfered at times when uploading), rebooted computer and reset the board but nothing works... I have connected an arduino UNO just to test another board and that works fine but communication with the leonardo is gone....!!
Could it be the bootloader? (I don't know a lot about it)
I have also noticed that on my windows port list the device is seen as "Teensy" (I used a Teensy for a previous project).
I wander whether this may also be the result of following the direction in this website: (MIDI device with a name of your choice) to change the device name. However, after changing the name it had been working OK for days, until today...
Another possible reason could be that I corrupted the bootloader. My code involved writhing char arrays in progmen...
Any advice ?
