Ok, so before going ahead I downloaded the so called Trial version of Adobe Aftereffects only to find having downloaded it immediately states "0" Days and asks me to purchase!!!!! WTF - the idea of the trial is to confirm its the right tool before we go ahead with full purchase - when your competitors offer free trials and to add salt to the wound you also have zero support rather throw potential clients to a Forum doesn't exactly present the right image.
Any ideas or have you restricted free trial to specific countries as example in which case should be stated.
Unfortunately, there is no way the reset the trial period. Unless you have another computer or want to format your hard drive, the only thing I can suggest is you subscribe. You have 14 days to cancel for a full refund.
Hope this helps!
