Trouble uploading megapirate ng 2.5.1 R3

Hi all

I have been following this thread and pulling a lot of useful info in building my soon-to-be-completed quad. However now all of a sudden, I came across an unsolvable mystery

Here goes: I try to upload megapirate ng 2.5.1 R3 to my flyduino mega board using the usb uart connector also from paul's store. I am on Windows 7, arduino 1.0 (and I also tried arduino 1.o relax patch). It will verify without errors, but hangs very late in the process of uploading. The led next to the ftdi pins flashes like when you upload firmware usually (I had mpng 2.0.49 and multiwii 2.0 on it) but then stops after just about 2 seconds. I read that "!!!" in the code can be a problem, searched for it and found it in one file of the megapirate sketch and in one of the libraries, and replaced it.

Output in the arduino console is as follows:

Code:
avrdude: Recv: B [42] 
avrdude: Recv: o [6f] 
avrdude: Recv: o [6f] 
avrdude: Recv: t [74] 
avrdude: Recv: l [6c] 
avrdude: Recv: o [6f] 
avrdude: Recv: a [61] 
avrdude: Recv: d [64] 
avrdude: Recv: e [65] 
avrdude: Recv: r [72] 
avrdude: Recv: > [3e] 
avrdude: Recv: $ [24] 
avrdude: Recv:   [20] 
avrdude: Recv: H [48] 
avrdude: Recv: u [75] 
avrdude: Recv: h [68] 
avrdude: Recv: ? [3f] 
avrdude: Recv: . [0d] 
avrdude: Recv: . [0a]
and this keeps on going and going and going and... you get the point.

Can anyone make sense out of this? Thank you guys for any pointers.

Cheers, Florian
