You're happy with your current version of Timeslips, not matter how old it is. The old Timeslips version is still working. You would never need to upgrade Timeslips if nothing ever changes in your environment. For example:
- You will never get a new computer
- Your current computer/server's hard drive will never crash
- You will never need to add more licenses
Unfortunately, few of us live in that world. If you order a new computer today, it will most likely ship with Windows 8. Only Timeslips 2014 is certified to work on Windows 8. If your hard drive crashes, you may be doing a "panic purchase" of a new computer. If your Timeslip software is obsolete, then you will be paying full price for a new Timeslips version.
We don't think you need to upgrade your Timeslips program every year, but once every two or three years at the most, you should seriously evaluate the pros and cons of a Timeslips upgrade
