Hi Omuletzu,
it seems like a weird problem with HIMEM.SYS and emulation of upper memory blocks usually set up by this command in CONFIG.SYS file:
DOS=HIGH,UMB
Finally the game itself cry about not using XMS memory that's provided by switching parameters once again in CONFIG.SYS file. It's maintained by
EMM386.EXE.
Please, attach here your actual
CONFIG.SYS and
AUTOEXEC.BAT.
I will read it through to find suitable solution otherwise your only chance will be emulation
