The Flex Master software license offers significant advantages. It enables users to build their own professional network by activating a file decryptor module and linking up to 99 slave users to their account. The Master version supports unrestricted file formats—users can work with plaintext files and .bin formats editable with any software.
Additionally, Master users can access Magicmotorsport’s file modification services and receive 300 free Green coins per month, along with full technical support.
The Flex Slave software license works exclusively with encrypted files, meaning Slave users cannot view or edit file content. Any required modifications must be sent to their linked Master for decryption and editing. Each Slave tool must be associated with a Flex Master account—either chosen by the user or assigned by Magicmotorsport based on geographic region. Once linked, the Slave remains exclusively tied to that Master for all file-related operations. Support requests from Slave users are first handled by their Master, and Magicmotorsport provides only basic tech support to Slaves. A Slave can be released only if their Master sends explicit written permission.
If you purchase the Slave version, you may upgrade to Master at any time.
The Helpdesk operates using a coin payment system with two types of coins: GREEN and RED.
Master versions of software modules include 300 Green Coins per month for Helpdesk support. Green Coins are non-cumulative and reset monthly.
