I had the same thing happen on one of our switches. Loaded the upgrade through the web interface and when the switch rebooted it had downgraded to 2.0p which I think was the factory installed firmware perhaps. I did the upgrade again through the web interface and after it rebooted it did come up with the 2.10 firmware. It seems to be fine after this, so I think it's OK to just run the upgrade again. I'm not sure if there was some other piece of firmware that needed to get upgraded first before it could accept the newer release or if it was just a glitch with the update code in my previous firmware, but it didn't seem to have any issues upgrading from the 2.0p version.
