Unable to run Repetier-Host (no replies)

Good day, everyone! Please give me a hand here:)
I cannot run Repetier-host neither from the terminal, nor via the desktop configuration file. What do I do? This is what I keep getting:

Could not set X locale modifiers
libpng warning: iCCP: known incorrect sRGB profile
