Can't get Back to my Mac to work on MBA

Question

I am trying to transfer files selectively from my MBP to my MBA. I tried to use migration assistant but it doesn't let you pick and choose the files only the broad categories. I thought I would try to use Back to my Mac and just access my MBP from my MBA.
I have BTMM turned on and all of the file sharing set. On each Mac I see the other in the "sharing" menu on the left side of finder. However, I cannot seem to log into my MBP from the MBA. I have no problem at all logging into my MBA from my MBP. Any suggestions for what I might be doing wrong?

Folders You Can Move to Your new Mac
From the Home folder copy the contents of Documents, Downloads, Movies, Music, Pictures, and Sites.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/ (copy the whole folder)
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)
/Home /Library/Calendars (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist
/Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft
For FireFox:
/Home/Library/Applications Support/FireFox
/Home/Library/Preferences/org.mozilla.firefox.plist
