owch..... burning smell is never good. it's probably time for an 
electronics tech for you....

One question - how did you cut the traces? And did you buzz your mods 
out afterwards?

The best way to cut a trace is to use a craft knife - like a heavy 
scalpel... first you make 2 parallel cuts across the trace, about 1/2mm 
(1/50") apart, with the blade pointing straight down, and a fair bit of 
pressure. Then to come back with the blade at more of an angle to the 
board, and try to actually lift out the 1/2mm section of track.... a 
small hand drill like a dremel with a bit that's wider than the track 
can do a good job too, but you need to be very careful that you're 
hitting the centre of the track with the drill to make sure it breaks 
contact 100%
