When the map file is missing, SA should place the .saencryptedreport file somewhere on your computer in case you want it again.
In windows xp/2003 it puts it in program files, in SmartAssembly's folder.
In windows vista and above, it puts in in ProgramData, again in SmartAssembly's folder.
You can just double click these (on a machine which does have the appropriate map file) to open them.
