I am not good with this kind of question, but I have moved it to the place where others are. Good luck.

Try this:

1. If you have any save games you want to keep, copy them out of the KSP/saves folder and paste on your desktop.
2. Right click KSP in your Steam library, click Properties.
3. Disable Steam Cloud for KSP.
4. Completely uninstall and reinstall KSP through Steam.
5. Right click KSP again, click Properties. Click Local files and then 'verify integrity of local files'. This will check the game files and redownload any that are corrupt or missing.
6. Run KSP (it should be plain stock KSP with no mods at this point) and check that it loads properly.
7. Copy the entire KSP directory out of Steam/steamapps/common and paste it somewhere else. It's a really bad idea to put mods in the Steam copy of KSP as stuff just keeps breaking that way, but there's nothing to prevent you from making copies of the game and doing so is the best way to use mods.
8. Put any save games you copied in step 1 into this new copy of KSP, add mods and continue playing as normal.

If that doesn't work, send the logs:
