Merging Projects in Suretrack 3.0

Question

I have several construction projects going on with different Construction firms. I want to make a master schedule of all the projects.I have asked for the projects to be sent to me via email using the Suretrack mail send command. The project arrives fine, but when I use the mail receive command to get the project I get an error to the effect "Mail message not in Suretrack mail format" I get this no mater what I try.I can copy the project to my hard drive and open it but then run into problems getting it into the master schedule.I am using Novelle Groupwise as my email program
