Help Problems connecting or invalid MMI code

[katyakatya5]

Hello. I'm Eka from Georgia, I'm sorry for my question, but I have problem. I'm a Xperia z3 user. I have bought it about 1 month. Yesterday i did update on Android (Now I have Android 5)... and after that I can't understand some informations about my account (e.x *100#, *135#), it writes for me - "Problems connecting or invalid MMI code", but Android, All apps, and Internet is working very good. Can you help me? or suggest for me some information? Thanks in advance.
