Just let me know.
The other possible problem is the web.config file. When you activate the solution it adds a line in the web.config file for the web application and when you retract the solution it removes the line that is entered.
It could be that for some reason this is not being updated when deploying the new solution. The part that is updated is in the <authorizedTypes> section. You should see the following line:
<authorizedType Assembly="SPD_SendEmailWithAttachment, Version=18.104.22.168, Culture=neutral, PublicKeyToken=acc221d0a4a7db74" Namespace="SPD_SendEmailWithAttachment" TypeName="*" Authorized="True" />
I would check to make sure that line is there and also that it is not duplicated.
If you want you can email me directly and I can send you my contact information and I can try to help further. To email me, just view my profile and click the contact link.
