Older Version of MYOB

Does anyone still use the old v19?  I went to confirm my company file today and was told I could no longer use it and I had to purchase new program! I purchased this program years ago and have never had an issue using it and don't wish to learn or train staff in using a new system when there is nothing wrong with the current system.  Does anyone know if there is another way to confirm my company file so I can continue using the original program I purchased? I paid a few thousand dollars when I originally purchased it and was of the understanding that this was ours to use forever...not having an expiry date!
