I am confused by sign in changes in the forum

I used to be able to log in with my username moshiachnow. Today I tried to do that, but it kept prompting me to link my log in with a Google log in. It also had me pick a different user name. So now I have this extra log in, geulanow, and no idea how I can log into my previous account. I tried resetting the password, got a new password, but keep getting logged into geulanow instead.

What am I missing here?

Thanks.

Really Confused Can Anbody Help???

Hi guys I have a Sony Xperia Z3 I had to have a new battery installed so I got it done had my sim card and memory card removed. When I got my phone back it had kitkat 4.4.4 installed which I thought was strange as I had lollipop installed onit before hand. I have tried the sony pc companion repair option and still its on kitkat the sony software is saying its upto date? Now here's the strange part I have no access to google services it doesn't exist on my phone anymore and neither does google chrome! Im really confused I can still get onto my google account online via pc just not on my z3 can anybody please help as my phone seems pretty much useless now as everything was backed up to google. Any help would be much appreciated. Thanks.
