Resolume 6 is 64 bit. Yay. That means that your old 32 bit plugins won't work. Boo. Can't have it both ways, unfortunately.
If your plugin causes a crash during startup, we'd love to take a look at the compiled dll. Maybe we can prevent the crash.
That will likely mean it still won't load though. To get your plugin to actually load correctly, you will need to get in touch with the developer. There is an
updated Git repo for FFGL, which can compile for 32 and 64 bit.
