The Solution:
1. Using an FTP program, go to your arpReach installation directory and download:
/application/config/config.php
2. Using Notepad or a similar TEXT editor (not Word), open the file and search for:
$config['sess_save_path'] = NULL;
... around line 385.
3. Change NULL to either:
/tmp
... or your server's temp folder path. The line should now read:
$config['sess_save_path'] = '/tmp';
4. Save the file and upload it back to:
/application/config/config.php
... replacing the existing file on location.
