Creating a backup file
Before deleting and reinstalling the software it's good to create a backup file of the Athlete measurement database. It can be done with the Export/Import tool.
In order to create the backup file, select 'File' - 'Export'. Select either 'Measurement Export' or 'Master Export' depending on which data you would like to save.
Save the backup file to a desired location on your computer. If you are about to install the software to another computer, it would be good to save the backup file to a portable memory, for example to a memory stick or an external hard drive.
When the backup file has been created, Athlete can be uninstalled from the computer. If you want to save the reports you have created and/or the possible files uploaded from your heart rate devices, copy also the Firstbeat Files folder from C-drive to the portable memory.
Athlete can be downloaded from Firsbeat websites. Note that Firstbeat Athlete has been discontinued in November 2015 so the new licenses are no longer available. If you already have the activation key (license) to Athlete, you can use it to activate the software. More detailed instructions can be seen here.
Importing the backup file to a new computer
When Athlete has been installed and activated, you can import the backup file.
This time select 'Import' from the File menu.
Select the folder where the backup file is saved. Importing the backup file may take several minutes depending on how big the backup is, i.e. many measurements the file includes.
When the backup file has been successfully imported, you juts need to reanalyze the measurements.
