Software protected by bios date - instructions included

I have an old software that works in DOS and is used to control a VRT system (vehicle road worthy test) This software has a software protection that works in conjunction with the bios date. When the software loads it verifies that the date embedded in a specific file corresponds to the bios date of the workstation, if the date in the file doesn't match with the date of the bios the software will not load and will give a "software protection error" I have a tool called [login to view URL] and instructions how to update the date in the embedded file but for some reason I cannot manage to get the software working. I have attached the software, the [login to view URL] tool and the instructions to reset the date. This is an old software and works in MS DOS therefore it might not work on new VGA cards. I found that it works fine with PCI/AGP vga cards. I require someone to provide me a step by step guide to use the upgrade tool and make the software work. The winning bidder must provide me with a screenshot of the mainmenu of the software as a proof that they managed to unlock the software.
