David, you should not need an update to V13, updates have ceased because there are no known stability issues. All work is now focussed on the new features in V14. If you are experiencing issues you may need to check/update some of the Microsoft Support Libraries in Windows.

eg https://helpcenter.websitex5.com/es/post/188230

If WX5 is crashing please provide screen shots or at least details of the errors you encounter and under what circumstances so that we can try and assist.

If your project is unstable, please either make regular uploads to the web (on each occasion a backup will be created by default) or export the project (step 5) which will create a standalone iwzip file for use in case of catastrophe. I find that good practice is to rename each after creation (eg add mmdd) so that I have a fall back position.

Hi David, 

I am very sorry for the situation. 

If you want to upgrade to version 14, to can find an upgrade discount in the "Offers" section of your Help Center account. Alternatively, you can subscribe to our Newsletter, so to be informed about any special offer. 

As to the issue with your version 11, unfortunately the direct technical support is no longer available, as you can see here:https://helpcenter.websitex5.com/es/post/154824

You can still get help by leaving this post as public, so to enable the other users to reply and provide you with further support. 

Thanks! I wish you a lovely day.
