If you plan to use Bitmunk Personal Edition from multiple computers, you will have to follow this extra step after you install the client on the new computer:
To use Bitmunk Personal Edition from multiple computers requires you to copy one file to each new machine you install the client on - your profile. Your profile is used to digitally sign all messages on Bitmunk so that the person that you're communicating with knows that they are talking to a trusted person (you).
Your profile is a password protected file and resides in the profiles directory under the installation directory of the Bitmunk Personal Edition software. The default installation directory is:
C:\Program Files\Digital Bazaar\Bitmunk Personal Edition\profiles
The filename is your username with a .profile file extension. For example:
johndoe.profile
This file needs to be copied to the same directory on the new computer that you installed Bitmunk Personal Edition.
