Modbuddy error, please help me !

[archerman59]

Good Morning,
I play videogames with Windows 8.1 (64 bits). I've some important problems on Modbuddy (Sid Meier's Civilization V SDK) and I want to resolve them because I'm making a map on worldbuilder :
-Firstly when I open the application, Modbuddy shows me this message :

Content Load error
System.Windows.Markup.XamlParseExeption loading "C:\Program Files (x86)\Steam\SteamApps\common\Sidd Meier's Civilization V SDK\Modbuddy\StartPage\Startpage.xaml":

'Cannot create unkown type '(dr-namespace:Modbuddy.StatPage;assembly=Modbuddy.StartPpge,Version=1.0.0.0, Culture=neutral, PublicKeyToken=33fba429992735]FixedMruListbox'.' Line number '131' and line position '26'

I tried to uninstall and reinstall the SDK, to install Visual Studio 2010 and some solutions which are on the 2K games' forum like http://forums.2k.com/showthread.php?117351-ModBuddy-Content-Load-Error-Cannot-create-unknown-type
but there are no changes.

-My second problem is very important and it is a blocking problem.
When I try to build my mod (to verify that there are any bugs, this message is displayed by ModBuddy :
------ Build started: Project: yoyottecity, Configuration: Default x86 ------
C:\Program Files (x86)\MSBuild\Firaxis\ModBuddy\Civ5Mod.targets(31,9): error : Civ5Path must be defined. Use the Project Properties window to set it to the location where Civlization 5 is installed.
========== Build: 0 succeeded or up-to-date, 1 failed, 0 skipped ==========
I don't find any solution and when I test my mod on Civilizations, the game crashes.

-Endly, when I launch Modbuddy, ModBuddy.Updater.exe starts and crashes every time without doing any update.

Those Problems prevent me from doing a real mod. I really want to play my map with a screenplay on Civilizations V as soon as possible. I can send you some screenshots if you want.
I hope that you'll help me,
Thanks in advance,

try launching your mod directly by opening the .civ5sln file instead of opening the SDK, that works for me

"Civ5Path must be defined" is solved by going to "Extras>Options>Civilization V" and then selecting "Use Custom Civilization V Path" and "Use Custom Civilization V User Path", then clicking on the "..." buttons next to it to select the folder.
I don't know about the other error.
