From where did you install? I can't repro that. I did download the plugin from the main git, install it to overwrite my own dev one, close and ran C2 again, nothing there. Then as your logs do speak about exporting which doesn't seem to be as you say directly after installing the plugin, I did try to export the project, I didn't get anay C2 error. Concerning the second topic, these are Webgl errors and not plugin errors, as for the slow connection that's C2's problem, most prolly because you switched window? They are not real errors as long asthey don't keep coming when you go back to the game
