Ok, i have uninstalled,
deleted the data in appdata
deleted teh registrys for valve
and also the square enix folder in documents.
run fff reg cleaner.
run CCleaner
now i've installed Steam again.
installing FF7 now.
Then i'm going to run the converter and see what happens.
EDIT:
Didin't work...
It there a way i can make regkeys or do the converters job manually (i see a nice sprinkles folder within the exe... and i have ahex editor and Notepad++)
Or can i alter the .bat somehow? (i know how to edit it, just not what to edit it to)
