Hi. I've just upgraded to Mavericks, and was using the apprentice license without any problem, but since yesterday Houdini just won't launch because it says the Houdini License Administrator is an old version and needs to be upgraded in order it can work, I uninstalled Houdini 13 and downloaded again so it may get the latest version for the Administrator. It keeps displaying that message, and when I try to run Houdini, automatically launches the administrator, with any license installed and displaying the error “The license server does not have a valid SERVER key”, for which I already tried logging in and keeps saying Wrong e-mail address or password. :? I'm sure the address and password are the same for the forums, because I didn't get any e-mail giving any information about log in in Houdini Online Services. It's real frustrating now, I'm about to go to Realflow please, HELP!!! :cry:

Looks like you're installling the network licensing not the local licensing - double check the installation options.

Well MartybNz I reinstalled Houdini double checking it wasn't a network license, and edward, I did step by step and still couldn't get any solution for my server key. Do you think it may be because it warns me about License Administrator old version which needs to be upgraded? Though it doesn't make any sense, it's supposed to be the one that I downloaded. I'll try downloading the version for Mountain Lion, MAYBE that'd do it.

hey, I just installed the Mountain Lion version and it worked! Now I can work again thank you guys for the help!!
