[AccessD] vbSendMail - Using with Access

To all,
 
I have the VBSendMail.dll which I normally use to send via via Visual Basic 6.0 applications, however I need to try using it with Access XP now, I have copied all my code over and registered the VBSendMail.dll, but when I compile my code I get the error message :
 
            User Defined Type Not Defined
 
And points me to this line:
 
            Public poSendmail As vbSendMail.clsSendMail
 
What am I missing has anyone used VBSendMail.dll with Access before, I have told people to try using it as I thought it should work without a hitch.  
 
Any help greatly appreciated.
