Whilst we’d love to be able to support the Ableton Live beta program it’s just not something we have the resources to be able to do.
If you wish to use our products with the beta’s and find that things don’t work as they should you can by all means let us know but we won’t be able to help you with them.
For support as an existing customer please use the Support Request section within your account page, this will enable us to validate your purchase automatically and assign the request to the relevant developer to respond when they're available.
