Welcome to our community, polachan
Sorry, but Adobe only provides the 30 days with which to try
it out. Once its over, its over. I'm doubtful support will offer
any help here as if they allowed any extensions, one could
theoretically keep extending and extending forever and never have
to buy the product to use it.
Your issue is one I regularly encounter. If you install trial
software where you know you are limited on time, you really need to
make every effort to use the time allotted. Personally, I'm guilty
of "multitasking" where I might have 15 minutes today, an hour next
week, half an hour the week after and maybe an hour the week after
that. Then BOOM! I've only actually used the product for about
three hours, not 30 days.
Cheers... Rick
