For all purchases of JStyle made within the past one year, there is no charge for upgrading to release 5.0. For purchases made before that, the upgrade cost will be as follows:

Please contact us (support at-the-rate-of mmsindia.com) for upgrading to multiple licenses.

When you are upgrading, first you will have to Unregister the earlier release. To unregister, select Help->Unregister JStyle from the main menu. After a few prompts, this will save an unregister confirmation code in JStyle's bin directory in the file unregister.txt. You will have to send this code to us along with the site code for registering JStyle 5. Without the unregister code your upgrade request is likely to be declined and you may be charged the full product cost. IT IS EXTREMELY IMPORTANT THAT YOU DO NOT DELETE OR UNINSTALL THE EARLIER RELEASE BEFORE UPGRADING. IF YOU DO SO, YOU WILL NOT BE ABLE TO OBTAIN A PROPER UNREGISTER CODE.  

Note: While sending the email replace at-the-rate-of with @. This has been done to avoid spamming.
