As i copyed the Plugin into the Engines Plugin, i had activated itin the Plugins. After restarting the engine, it told me, he must recompile the plugin, because it was precompiled with another Version.
But he could, it tell me to do this manually.
Rebuilding the project throuth Visual Studio succeeds. but still cant open my project, cause of the plugin compile error.
I am using 4.13.2
