You can't link images like that. You first have to upload them somewhere like on imgur.com
Anyway, Grimoire 3.8 its bot menu doesn't work indeed. You can load bots in the 'misc' tab, and click 'load bot'.
And the loading problem is likely not an issue with the bot. But with your cache files. Some AE staff even retweeted to clear your cache recently, so seems like it also happend to regular players in the last update.
I'm not entirely sure where Grimoire/flash stores all these files. You could try
Control Panel >Flash Player > 'Storage' tab > "Local Storage Setting by Site..."
Then remove these 3:
Or use some tool like CCleaner that clears all these files for you. Several have responded that this fixed it.
ps: for future reference, these things are better asked in the help section. Someone even asked the same thing yesterday btw.
