Motorola: another company I'm not too keen on

I have a Motorola RAZR phone and bought the software to connect it to my PC. This was a few years ago. A while ago I started up the Motorola program and it told me I could update to version 5 for free. So I said yes, it downloaded the new version and rebooted. Then I ran the new software and it said "Your phone is not supported." Gee thanks a lot Motorola. Fortunately I was able to restore version 4 and all was well again.
