Launcher Problems!

After solving 2 problems regarding my RelicCOH.exe not being in the right place and my launcher not showing "Play" and "Update" , it seems that starting the launcher maximised stopped working suddenly , I get an error message when doing so , saying that my languages file is missing and that the launcher will open in English. The launcher then opens without opening "Play" or "Update".
That , plus maximizing through the Applications tab doesn't work for me.
Any ideas?

Try change your DPI, check the sticky for info, also try to change it in the shortcut (run) - maximized
