Thanks for reporting.
Does it not load at all, or only take a long time? Please give me some information about your system, like the CPU and RAM you have and whether you are using an SSD or HDD (disk drive)?
It might also help if I can have a look at your log files just in case there was an error.
For Windows the log files can be found at: %USERPROFILE%\AppData\LocalLow\jakai\tentikun\
and Linux at: ~/.config/unity3d/jakai/tentikun/
