I have tried to play using the current trainer but it seems incompatible as only some keys work and only once at that No 2.3 and 4. As trouble shooter says use proper version I.E. V1.01.
EDIT. Just to clarify I do have a retail copy pached to v1.01 NOT a copy as I read the inference. and I have just loaded it again and read the small print It appears that you have to mouse over the required item or building then press the appropriate key. I assumed that it worked like all the others. F1 to activate then press a key for what ever function required. teach me to read the info in future.
