bowtie called me a monkey by thanking me
he's mean...
edit: i didn't want to add another useless reply, so i'll add to this useless one.. the registry is where that stuff (license, validation etc) is normally kept for programs. it should be difficult to lose this information, normally. something has to actively search and remove it or it wasn't allowed to be written in the first place.
make the game run in administrator mode... maybe it isn't allowing the registry edit due to some windows securtiy.
