Email Button in Acrobat 7.0 Standard

I have the Problem that I have a genereated PDF document that works perfectly. The only problem is that I want create an Email with that document attached directly from Acrobat (File -> E-Mail). It works normally everytime that the email is created correct, but after you did that Acrobat itself crashes everytime! In some cases the Mail is also sent twice.
(Email Client is Outlook XP)
Do you have any solution for me?

Thanks in advance
Best regards

Markus
