Hey all,
I've recently come across this infamous error as well and the solution that solves it for me is to simply restart my PC. I can then safely launch into LSPDFR without a problem (version 4.1.0). Although, when I go on duty the LSPDFR plugin crashes and I need to reload all the plugins through the F4 console by typing "ReloadAllPlugins". After that, I can usually go a 2-3 hours without any problems.
If any of the devs read this: maybe there really is some sort of corrupted memory that is purged when a PC is restarted?
Hope this solves it for some people.
