How to get an UFL into Crystal Reports 2008

Question

Hello,
I created an UFL in Visual Basic, built .dll, registered it successfuly with RegAsm and added to GAC. Yet I still can't see the functions in Additional Functions.
DLL source code:
<Runtime.InteropServices.ComVisible(True)>
Public Class Class1
    Public Function UFLTest1() As String
        UFLTest1 = "Hello"
    End Function
    Public Function UFLTest2(ByVal sVal As String) As String
        UFLTest2 = "Hello, " & sVal
    End Function
End Class
In VB project properties, Make assembly COM-visible is checked. .NET framework 3.5 has been used. I copied the .dll to directory c:\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\ and registered by RegAsm from there (and added to GAC).
Any idea what can be wrong ?
Thanks,
Jakub

Ok, solved it.
If anyone fights with writing UFL, check [Microsoft MSDN|http://msdn.microsoft.com/en-us/library/ms227603%28v=VS.90%29.aspx] and follow it step by step (and I mean STEP BY STEP, any single checkbox missed and it's not gonna work).
