Dimension Bx xyz resetter

Hi Guys,
Please help. I bought the xyz resetter from Dimension BX and it does not work. I have tried the old firm ware and the latest firm ware. I the software tells me that the cartridge is reset to to 240. When you load the cartridge back in to the printer, it tells you that the cartridge is low and to replace the cartridge. Is any one else having this problem or is this a isolated problem. Please help me sort this issue out. Dimension Bx refuses to help me or even entertain my emails to them. At one point, they said that they would refund me, but they do not answer my emails. So if any one has any ideas, please get in touch with me tru the forum.
Thanks for any help from any one.
