Hi!

I have 8.1 sitefinity website and I am using tool of version 1.0.0.7

But I am receiving next one error:

Telerik.Sitefinity.Compiler.exe Error: 0 : System.Runtime.Serialization.Serializ
ationException: There was an error deserializing the object of type Telerik.Site
finity.Web.Compilation.PageKeyResponse. Encountered unexpected character '<'. --

Can someone give me idea how to find a reason why this happens?
