Email

My operating system is Windows XPSP2, email client is Groupwise 6.5. When I am in Acrobat with an open pdf and want to send the pdf by email, I select File, Email. My email client launches and creates a new mail message, but the pdf won't attach and fails with this Microsoft error signature:
 
AppName: acrobat.exe AppVer: 7.0.8.218 ModName: gwmlt1.dll
ModVer: 0.9.24.0 Offset: 00003272
 
Any help would be greatly appreciated.
 
Karen.
