I have created a project, in trial version. But now I can not login with my account as it says "You need a Sparkol PRO account to use VideoScribe. You can only take advantage of the trial once." I am going  to purchase the pro version now, would my project be remained save, and can I export it without watermark of the software in pro version?

After you subscribe you will be able to login and access any projects you have saved locally on the same computer, or online.
