Hi,
Sorry for the frustration with the translations. We are working on getting this resolved.
It is not an issue with the coding and thanks for the offer to access your site, but out policy is to not access customer sites.
The packaging process we are using is not getting the latest translation files from GlotPress and because of that the translations are broken.
Although the translations may look complete in 3.10 we introduced a filter and any translation string with the word event in it has to be updated or it will not work.
You can get a copy of the translation that should work from here:
http://translations.theeventscalendar.com/projects
Download your .mo and po language-files for the project
Upload them to the plugins language folder
Rename the two files to tribe-events-calendar-es_ES.mo and po (Spanish example) I think German is de_DE.
Let me know if you have any follow up questions.
Thanks
