I recently downloaded the trial for photoshop (30th aug for exact) but today I opened it up to continue with my work and it told me that my trial has expired. With today being 2nd sept, you can see that it definitely has not reach the expiration date for the trial. I need to finish my work for monday, some help would be much appreciated thanks!
I think you're stuck. For some reason the 7-day trial ended early (it's timed from when it's downloaded, not when you first use it). The only solution, if you can't access an earlier version or someone else's, is to download the trial on to another computer. It's not recommended to use trial versions for important work - which is not much help for you at this stage!
