updates, translations, BCC e-mails, Invoices

Hello,
I encounter some various small problems with my version of GeoDirectory, are not arriving alone, I come to you to ask for help:

1 – Updates.
I can’t update some plugins because the registered license numbers and my updates license numbers are not the same.
How to change those license numbers (these plugins are :Advanced Search, Custom Post Types, Events Manager, Location Manager, Payments Manager).

2 – Translations
I translated 100% of the files to be translated, though, there are some translations that do not. This is the text “featured” which appears in photos ads, it is “my invoice history”, and it is also the text of the ad verification page on the front office (images attachments).
Or should you go to unlock or force translation.

3 – Copies of emails.
I disabled the sending of all mail copies sent to clients, I get them anyway (image attached). How to disable them succeed?

4 – I can send an invoice to my client, by cons, it is impossible to view or edit it for me. How to make it work?

5 – We wish to import data stream, but we encounter the following problem. When there are accented words, imports do not work or work poorly. The letters that pose problems are: “é”, “è”, “ô”.
If one of these letters is in the title, region or city, the import will be done does not work in the front office. How to solve this problem?

Thank you

André
