Hello all umbraco lovers :)

for a new project i created a new umbraco (v4.5.2) wich looks awsome btw :)

but in my usercontrol as soon as i use the code:

Document doc = new Document(umbraco.presentation.nodeFactory.Node.GetCurrent().Id);

string flickrFeed = doc.getProperty("flickrFeed").ToString();

i get an error:

Could not find file 'c:\windows\system32\inetsrv\umbraco.cms.businesslogic.property.Property'.

the server is running umbraco 4.5.2 (.NET 3.5)

any idea what is causing this error and more important how do i solve this?

Regards,

Nick
