Hi,
Thanks for reaching out to us. Please note that as maintaining a high quality up-to-date product with technical support requires continuous effort on our side, we have to be relatively strict with our licensing fees and are not able offer long-term trial extensions. We offer a 30-day trial period to help our prospective users understand whether our products match their requirements/expectations and can be used in their environments, but unfortunately we are not able to provide any free offerings beyond that.
That said, we might be able to provide a short trial extension in some cases (e.g. where you could not evaluate specific features/scenarios). If this is the case, please feel free to contact our sales with a detailed description of your situation and we will get back to you shortly.
