Because you're forcing DX11 or openGL.

Hello and welcome to the forum.If i have to blind guess,you need to update SmokeScreen .
 

Hello,and welcome to the forum.
Did you install these mods via CKAN?You have two other (older) instances of MM installed,which are unnecessary.Also,try to manually install this USI tools.

EDIT:There is a similar problem in MKS thread:
 

AXIS_MOUSEWHEEL { PRIMARY { name = Mouse ScrollWheel axis = -1 inv = False sensitivity = 1 deadzone = 0 scale = 1 group = 0 modeMask = -1 } SECONDARY { name = None axis = -1 inv = False sensitivity = 1 deadzone = 0.0500000007 scale = 1 group = 0 modeMask = -1 } } You can change that in game.But if you decide to do this as you did then you can freely delete settings.cfg and on next start it will reset it self to default and create new settings.cfg.

You have forgot the brackets.
@PART[CA_ET,CA_ET_extension,CA_ETnose] { !MODULE[FSfuelSwitch] {} }  

It should work as it is,the only thing you need to change is:
category = Aero also make sure you put "InflatableHeatShield" folder in ...GameData\Squad\Parts\Aero

I presume that you're using Remote Tech.
@PART[*]:HAS[@MODULEModuleRTAntenna]]:Final { @MODULE[ModuleRTAntenna] { -MaxQ = Del } } This MM patch will remove "snaps under high dynamic pressure" from all antennas.

Hello and welcome to forum.The information you provided is not enough to successfully troubleshoot your problem,but the obvious question is,did you also install Module Manager?If yes,then please read:
 

@Svm420,if you're on windows
 

@Voodoo8648,this is normal behavior of solar panels,farther you are from the sun,less energy they produce.

@Numberyellow, @Racescort666 Try to look in: C:\Users\"name"\AppData\LocalLow\Squad\Kerbal Space Program
If your AppData is hidden just type(copy/paste) the following in search bar:
C:\Users\%USERNAME%\AppData\LocalLow\Squad\Kerbal space Program  

@Whovian41110,this is most certainly a debug arrow from MJ2.
In MJ panel look for "Attitude Adjustment" and and you'll see you have checked "Command Pod Forward".

You can change buoyancy in physics.cfg.Everything is well documented and is patchable with Module Manager.
@PHYSICSGLOBALS { @buoyancyScalar = 1.2 // Scalar to buoyancy force }  The other method could be to edit parts buoyancy
@PART[*] { %buoyancy = 0.2 // You can try negative value or 0 %boundsMultiplier = 0.7 }
