I'm in dire need of a working RSS for a couple of MT6000E's (ex UK police). I have the software for the MTS2000 and I figured that would work on the MT6000E as well as it seems basically the same radio, but if it only were that easy

From posts here and there I gather that I need one of the following:
GP-900-99-Channels (MT6000E) R01.00.00 20 Nov. 1996. EVN4653A. (99 Channel version of GP900).
GP-900-99-Channels-LAB-MT6000E. NVN4602. R02.00.00. 24-August-94.
Can anyone help me out? I need these radios programmed tomorrow morning
