WinRAR licence expiry?

Hi everyone,just a quick question, I have just re formatted a new sd, and noticed when applying latest kernal that I put on my pc a couple of weeks back that in the title window or winrar (blue bar at the top of the browser) it said 'only 19 days to buy a licence '- anyone know what this means and if I need to do anything???Thanks in advance.

Don't worry, after that time runs out, all it'll do is suggest you donate money every time you use the program. Just click the "close" button on the window that pops up, and it will carry on working fine.

You can still use it after the trial is expired.or use the alternative rar program, 7-zip.
