title: Updating CKFinder 3.3 to 3.5 requires a new li8cense
body: <p>I have Enterprise license of CKFinder 3 and currently using CKFinder 3.3 with Asp.Net.
  .Net Framework 4.6</p>
  <p>I upgraded from CKFinder 3.3 to 3.5.2.
  For this I had to changed project's targetFramework to .Net Framework 4.6.1</p>
  <p>But after updating I see this message &quot;This is a demo version of CKFinder 3&quot; on the page where CKFinder is used.
  I didn't get this message on CKFinder 3.3 and I'm using the same license key.
  If I revert back to CKFinder 3.3 that message goes away.</p>
  <p>It seems that updating from CKFinder 3.3 to 3.5 requires a new license.
  But on an old CKFinder forum it's written that purchasing a yearly subscription will let us update CKFinder. <a href="https://ckeditor.com/old/forums/Support/License-CkFinder" rel="nofollow noreferrer">https://ckeditor.com/old/forums/Support/License-CkFinder</a></p>
  <p>Do I need to buy a new license to use CKFinder 3.5?</p>
