So until I get a chance to recompile from scratch I thankfully managed to find a back up of an old exe and the original source files.
I hope this is useful to you in the meantime.
I have designs on making the update and compilation script as automated as possible so that I can much more easily produce updates when any bugs come up.
I’d also like to create an admin interface to make it easier for users to add and remove users and groups.
Thanks for bearing with me.
