I've been running 3.00jb for many months. I just tried updating to 3.00jj but in the plugins pull down in sketchup there is no Irender load. There is a Irender beta load that will obviously only load 2.0 something. I've tried installing twice, uninstalling once and then reinstalling, only to get two entries for the beta load! I've looked at the plugin directory in \google\google7\plugins and can see the scripts sitting there but they won't appear in Sketchup! I have win32api.so in the plugins directory and Irender_loader.rb, Irender_Nxt_loader & Irender_Nxt_beta_loader.rb (dated 23/10/2008,15/09/2010 & 24/09/2010 respectively!).
Any help would be greatly appreciated...I can't think of any other way to get this to work!
