Update Solidres Plug In error

Hi
I have been using the Solidres reservation plug in for some time now. As with all software I keep getting notifiers from time to time saying it needs updating. The last few times (at least 4 now) that I've updated it, the booking system has fallen over and I've had to roll the site back to remove the update! The "Select" button disappears from the reservation screen so it's impossible to progress to the payment options screen. Only a minor detail I guess, not being able to book with a booking system! Can anyone advise or help please as this is a critical error and if I can't resolve it I'll need to find another booking platform.
Regards
