I urgently need the trial for work.
Where is the logic in that? If you need something for work, you pay it. The rest we cannot know. You have not provided any system info or anythinge else that would be useful. Either way, there's probably nothing anyone can do. Once trials have locked up, only paying for the product and properly activating it will revive it, but even that is doubt ful since you very likely have a technical issue that causes this problem.
So you try to 'help' me by basically calling me illogical. I'm not gonna pay for something that I'll be using for only a week.
Anyway, I've found a solution to the problem, which doesn't involve payment. Thank god.
You sure it's legal to use the trial for commercial work?
