yes, I am having the same issue. I do not know if this is related to the new hud 16.7b will not allow any web GL connection as well it gives the same error as trying to connect to the sl meter page. .
I am still unable to get tools from server to my hud. I relogged as well as got fresh HUD. Vudon is the sim owner of one I am on and he said he reset his server. Any ideas?
For anyone else who hangs out at Crimson Hollow and happens to have the same issue with tools not populating in the HUD, what Vudon did (and apparently Doogz also?) was to use Get Tool instead of Use Tool. For some reason, this kick-started the HUD into populating the existing tools.
