Has anybody had any experience with this book on XPP? I've been struggling with this problem off and on for months.

Error Type:
Microsoft VBScript runtime (0x800A01AD)
ActiveX component can't create object
/site.asp, line 42

Which is:

Set m_visit = Server.CreateObject("WroxCommerce.Visit")

I have painstakingly followed the text and the errata only to find that the book changes OS's in chapter 9. If you want the email functions to work you must have IIS and not PWS. So I installed XP Pro and everything seemed to go O.K. until I came across this error. I am absolutely stuck. I've quadrupled checked the code and I've even re-installed the MS Scripting library. I think that it might be in my permissions. IIS will create other objects from the same root directory and it seems to be working fine. My SQL Server is on another box and there is not any indication of a problem with that. Perhaps there is a default setting on XP that needs to be changed. I know that when I configured the debugger in Interdev I found some differences. Can anybody help?
