Default Kit Kat / PC Suite

When I had root and recovery an OTA Update came up like 2-3 days ago and I decided to update but I stuck at bootloop with TWRP but anyway I fixed my phone and flashed the kdz Stock Firmware. But now when everything is okay and I go to the Update Center there's no Kit Kat update on there and it says I'm with the latest OS.. I tried updating over PC Suite but when I try to search for an update it says It failed connecting to their servers and nothing happens.. Is there something I can do about?
