Missing items and old login screen?!

Okay, so I uninstalled/re-installed pintos in hopes of fixing some textures that screwed up for no reason. after i re-installed i logged on and the login screen was different, it was the older version, anyways i login i see my characters click on one, and when i got in-game i noticed items were missing like armor,weapon skins, custom items, etc. please how can i fix this?!
