Are you currently blocking the program from connecting out? That can sometimes cause the loading problem.
The Offline version shouldn't need to be blocked anyway.
If you can turn your internet off, do that (as
sacredsin suggested) and unblock glamour-server.exe (Glamour_Data/StreamingAssets). glamour_server is just there to fool the program into thinking it has a connection to Silver's server.
I wonder how many people have made the mistake of blocking Glamour.exe instead of the fake server program instead.
You could also add an exception to your firewall for the Offline version. ("Allow"). As the Offline version contains all assets and requirements, it doesn't need to connect out.
Lastly, make sure it's not in any system-critical folders (like C:\Windows, C:\Program Files (x86), C:\Program Files or C:\ProgramData). If you can, put it on a second hard drive. All my games are on that second drive.
The easier way would be to create a new folder somewhere (some suggest the desktop, but that can get cluttered quickly) and use that. Make sure you have read AND write permissions for any folder you create.
And for the Appdata/LocalLow/SandlustGames/Glamour folder.
The free Online clients are actually
not the full versions they purport themselves to be. For example, 0.18 (the one and only time I've tried using a free online client) was not actually 0.18 - some features of that release were missing. I'd suggest hanging back and for 0.21 Offline. We'll get that when the $5 patrons get 0.22. I don't feel the game is worth dropping a few shillings on it yet.
