Hi my name is Hakp. I play thw TW version of the game and i had problems with redownloading the game because after I did the lanch i would get a c++ error. the problem was the lang0.pak in the game files. it was outdated. the answere was to download the new lang0.pak from http://www2.zshare.ma/ytzo0tdh18qs . downlaod the link on the bottom right,delete he old lang0.pak ans post the new one their. The guy who help me with this was Deucalian. He deservs all the credit so thank him if this helps you.
Worked, I reinstalled, removed any english patch files, patched through launcher but did not press start. I just replaced the lang0 with new one after patching and right click the dbo.exe application file instead of launcher and ran as admin and it worked!
