To make the Acceptable Language option (on your campaign settings) works, and you want the bot able to fake Timezone by IP/Country. Your proxy list needs to be GEO. Using the GEO Tool will help you. Just drag your proxy list to the main windows, click GEO & Save.
The GEO tool uses the database from MaxMind. You should update the GEO database as the database in the download may be too old!
Requirement : .Net Framework 4.5.
Your proxy list after GEO looks like this (with country code and Timezone offset at the end)
184.108.40.206:54566;;;FR;1 220.127.116.11:8080;admin;password;US;-8 18.104.22.168:8080;;;RU;3 22.214.171.124:3128;;;US;99 126.96.36.199:54566;;;IT;1
