Errors in .exe after build (maybe caused by not correct reading xml files)

Hi, today I wanted build my project and everything seems to not work! Only few script are working. (In editor playmode everything works perfectly) When I build project with developer build and console there are a lot of null refrence exeptions.

So I opened "output_log.txt" and here I have many: http://pastebin.com/5g1bYej8

But after few lines I have this:

IsolatedStorageException: Could not find a part of the path "G:\testInz\Nowy folder\Dark Time_Data\Resources\Text Files\Inventory\Consumable\DATA_Items.xml". at System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options) [0x001f9] in /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.IO/FileStream.cs:290

And after this there is avalanche of errors which probably are caused by not working xml rading (when path is correct in editor there is avalanche of null references too)

I created my xml reading classes based on this example: http://forum.unity3d.com/threads/add-multiple-language-support-to-your-unity-projects.206271/

So I using Path.Combine function to get xml files, maybe I should use something else to make it work in build? My .xml files are in "Assets/Resources/Xml Files/" Folder

Thanks.
