v5.1 is the emulator, after unzipping it will be an .exe file. You are best getting the version over at Desertislandfruits.com.
To make a .fml file, you simply load the .dat layout into mfme v5.1 and then go to close it, it will say save yes or no, say yes and it will automatically create a .fml file, which can be used in the latest version v19. You'll need to do this for all .dat layout files, you want to play in v19.

Donating at DIF is not compulsory, but you'll get restricted download access. Donating gets you full access to everything and support from people like me, who will appreciate the fact you have made a donation.
Amazing thanks, I found it on there now and opens fine.
