First time posting here, but I do hope this entry will help out a lot of Zhu Xian players out there. :D
If you prefer a full version of the ZX OBT client, you may try an alternative download hosted by Seitoukai.NET. It's the same with the one at the e-Games site, only difference is that it's not divided into 16 parts, and you get to download it full. That way, you get less problems with the downloading and installation process.
Feel free to try the alternative download at this link.
I really hope this helps! ^____^
