[krisavi]

I tried even deleting configuration, still not able to access buttons

In log file there were few errors with encodings

Fix procedure:
Go to KER directory (KSP\GameData\KerbalEngineer)
Open each xml file (most will be in settings folder) and change in first line file encoding from whatever you have (windows-1257 or other) to utf-8.
Save all xm files, run KSP and enjoy fixed KER gui.

Fixing xml file with hands doesn't solve problem. After launching ksp once, it will overwrite xml file. After that, you will face same problem again.

[krisavi]

@calanchue is right, fixing it manually doesn't solve it.
Why would the file even change the encoding by itself. On one launch it is ok and then it messes up. Had to close the game, remove all the config files and restart game to get it kinda working again.

For some reason I have to remove files every time, to launch the game correctly, because as soon as the game closes next startup it will be broken again...

Seems like mod or game itself messed up encoding and then it wasn't able to read it.

Shouldn't the mod be able to fix that error programmatically?

[Y0ssarian]

Well, It did not overwrite for me. I changed it once and everything is ok since then.

[calanchue]

Sorry, That was my own fault. your uploaded version is totally fine!
Cause was my own mods which intend to fix the problem from outside of KER.

Thank you for your help. maybe you saved a lot out people out there.
