sounds very strange indeed matey ..not sure what it could be ..you sure you have the 1.04 trainer ? right trainer right updated exe?
you can put the trainer its self on the desktop if you like no need for it to be in the same folder

now to start the game to use the cracked exe ..you should have a shortcut on your desktop that leads to something like this
whatver drive letter you have the game installed to :\Program Files\Ubisoft\Tom Clancy's Rainbow Six Vegas\Binaries\R6Vegas_Game.exe"
for example i have my game installed in my E:\ drive so the short cut is
"E:\Program Files\Ubisoft\Tom Clancy's Rainbow Six Vegas\Binaries\R6Vegas_Game.exe"

All you should have to do is ..run the trainer then dble click ur shortcut to your cracked.exe and thats it

its a buggy game ubi have deserted it regards support etc

if this doesnt work get back to me ..we can have another look
