"Fatal Error" with plugins

Hello, I’m having an issue with using my plugins (Plini and Fortin Nameless). I can get the standalone to work for 10-15 minutes and then I receive a message stating that the exe. could not be loaded and that corrupted data was read. On top of that, whenever I scan for the plugins with REAPER I get the same error message when they’re found.

Any help in the right direction would be greatly appreciated, thanks!
