I finally saved up enough and sent my ECU off last week.. I tried to save a little money by sending it to Tactrix, but with all the shipping it costs about the same. I explained my issues to Tactrix support and he said because my laptop is 64 bit i should be using the beta version of ECU flash. This time i am going to try using the beta version and copy the files to the original rom like you said. Fingers crossed, wish me luck.
