Hello,

I've tried to install uBlogsy 2.0 B2 on Umbraco 4.7.1 (Hebrew) by using the "install local package" menu and pointing to the downloaded zip file. Toward the end of the installation I got a dotnet Exception error message:

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

and a stack trace (listing a few lines)

[NullReferenceException: Object reference not set to an instance of an object.]
   uBlogsy.BusinessLogic.DateFolderService.GetCorrectParentForPost(Document doc) in D:\_PROJECTS\uBlogsy - Blog\Branches\2.0_beta2\uBlogsy\uBlogsy.BusinessLogic\DateFolderService.cs:186

   umbraco.cms.businesslogic.web.Document.MakeNew(String Name, DocumentType dct, User u, Int32 ParentId) in c:\Dev\4.7.1\umbraco\cms\businesslogic\web\Document.cs:429

However, I do see now the uBlogsy entries in the content tree, but if I try to preview a blog entry I enter into the uBlogsy fields I get:

"Error loading Razor Script
Cannot perform runtime binding on a null reference"

Any hint would be appreciated. Please note that I am not a .NET programmer and I have installed Umbraco on a fairly fresh server2008R2 system (it has dotnet 4.0 installed) a few hours ago (Used the "blog" starter package and that went fine).
