Doesn't seem to work for me
"Translations for new game write-ins in this language cannot be accepted at this time!"
That's strange. I've submitted a translation for a new game just fine, two days ago. Are you really trying to submit a translation? If true, to what language?
If nothing works, I'd recommend you to contact RH.NET staff
. In the last months, everytime I had a problem when submitting translations, I contacted the staff to report the issue, and provided all the steps needed in order to reproduce it. Until now, all issues reported by me were fixed, and it shouldn't be different in your case.
