How do I back up my data?
Backup the data folder complete with its sub folders.
Each users data is stored separately and the location depends on which version of Windows you have.
For Vista and Windows
7 it is
C:\Users\(Your User Name)\AppData\Roaming\M8 Software\(Program name_Data)
For Windows XP it
C:\ Documents and Settings \ (User Name) \ Application Data \ M8 Software \ (Program name_Data)
For Windows 98 it
C:\ Windows \ Profiles \ (User Name) \ Application Data \ M8 Software \ (Program name_data).
