OTT isn't working on FL 12.5

I've just installed OTT. But when I go to my DAW and load up OTT, it immediately says "Plugin crashed during processing." It doesn't work when I reload the plugin nor when I reset the plugin properties. I tried installing in like 5 other directories, but nothing seems to work. What should I do?

Try the 32 instead of 64-bit version or vice-versa, try installing just one of the two at a time.

Thanks! I've just realized I was always running 32-bit FL Studio version, that's why it didn't work xD
