Ethos.Excelsior

So after wading through pages and pages and pages of information I cannot find a clear explanation of the problem I've been having. When trying to add kethane parts to something in the VAS, the part is not added, the attachment node vanishes, the part sticks to the cursor, and the program becomes generally unresponsive. The only two mods I have installed are this and the most recent version of kethane. I am using version 0.21 and I have replaced Launchpad.dll with the file provided in the main thread. Kethane operates fine without this mod installed. I'm assuming that there /is/ a way to have both mods operate at once, but I've just not been able to find some critical bit of information in no uncertain terms.
