Hi ! Thanks for looking in interest of this game. Although I've never really encountered any technical issues (other than occasional crashes); here are some that might help:
1) The computer has enough usable RAM space.
2) The game client completely finished downloading and is not corrupted.
3) Left enough time to progress.
4) Computer is clear of virus, malware, or any potential threats.
These are the only possible ways I can think of as of now. I'll keep you informed if I find more solutions.
PS: Make sure there's no banana inside your CPU, damn those bananas >w<________________Nyaaaaa~
