Not an expert by any means but I know that you can get problems if the computer to which the embedded file is sent does not have the source file. When this happens, you can use an option to convert the embedded file to a file format you can use.
To convert, right click on the embedded object ( in the source file )
On the shortcut menu, chooes object, convert.
Select the format you wish to convert to and then click OK. The file should then have been converted and should be able to be transferred to the other computer as a file it can read.
Not sure if this helps
