I got the file from Flashcut after sending in my serial number. Unfortunately I am having the USB connectivity issue described in this thread.
*edit* I solved the connectivity issue by installing the Torchmate driver. Couldn't find a download on the Flashcut site, but they seem to be interchangable. Apparently the Flashcut software does not install the driver for the 501A, and you have to do it manually. Link:
