Help i messed up my game

[Melissa Bellisserian]

I was in advanced and i think i changed something but have no clue what. I see all menus/windows are huge and unable to use the game. I tried reset but didnt help

Using any of the Advanced or Develop menus is risky, so you should leave them alone unless you know what you are doing.  Fortunately, though, the solution to a problem like yours is fairly simple.  You will need to delete all traces of the viewer from your computer -- including all hidden files, where those settings are stored -- and install a new copy.  The process is known as a Clean Install, described here >>> https://community.secondlife.com/t5/English-Knowledge-Base/How-to-uninstall-and-reinstall-Second-Life/ta-p/1375231

Sounds like you changed the User Interface scaling size in the preferences panel, if you cant manage to find and alter that, you might have to do a full clean install, which would mena uninstalling the viewer, then going to the C:\Users\[your windows login name] subfolders where your viewer stores your personal settings and deleting those too, then reinstalling the viewer.
