I got the Translation myself now.
I would like to tell you all some things:
1. the Version 1.62 update can be downloaded even if you don't have the Translation addon.
Apparently the update can't be installed if the Translation is present.
2. The dropbox link in the mentioned post 17 links to the patch to Version 1.60!
This is not Version 1.62, at least according to history.txt.
Thus you can't use it for a Manual update to Version 1.62.
3. For the Moment I can also confirm some game breaking bugs and other smaller issues for when the Translation is in place:
- using strateghy items might cause a game Crash with error 7.
- Atempting to store or take out items in the item warehouse causes another Crash with error 7.
- The descriptions of some weapons is in the wrong order, meaning that the Name of a weapon is spoken correctly, but the description is not the right one.
I currently don't have efull examples, but I think some weapon got wrongly described with the attributes of one of the needle launchers, allthough the weapon in question was not the said needle launcher.
Attention!
Switching back to Japanese won't fix the game crashes!
If you update to Version 1.62 without placing the Translation file into the game Folder, you won't get many Errors for common things like using items or going into the warehouse.
