When I click the "文库”， it just show “500 server error” What‘s wrong with this? These days I can’t learn new program！
Sorry about that, it looks to be an issue with the translation. We’ll look at getting this fixed ASAP. For now I’ve changed your interface language to English so you should be able to access the Library.
OK, this should now be working. Let us know if you come across any other issues!
