Font problem under Vista

I've got some problems executing the game under Windows Vista.
I've got Space Empires IV Gold patched to Deluxe and then patched to ver. 1.95. The very first executing of SE4Gold showed font problems: no text is seen both in menu and further within the game. Patches gave no result.

However, Vista has got all used fonts within its font directory; they are named by default, though - as far as I can see - within the game these font are used under some abbreviations (SE4blk1s -> SE4 block 1 small, etc.) On the other hand, font files in game subdirectory are opened as 'empty', but simple copying similar files from Vista dir into the game gives nothing: as soon as they get in, they become 'empty'.

The game had been executed with administrator rights.

What can be done with this if possible?

Thanks for any help.
