This behavior is not normal for the Grid for .NET. Since updating your code, are you initializing any Xceed objects or using Xceed classes before setting the LicenseKey? If you are setting the keys in your main method or the entry point of your application before any classes from Xceeds assemblies, then the license keys should work without a problem.
