Export does not work

[johnr201611]

I am using Lightroom 6.14 on a laptop which worked fine until yesterday.  I am no longer able to export photos.  (When I do, the photo that is produced shows none of my editing changes.)  The export window appears broken.  I can't, for example, check off the watermark box.  

I uninstalled and reinstalled Lightroom, but still have the same problem.  I am also, for the first time, getting the error message that my serial number is already in use by the maximum number of computers. This is not happened before.  I do have the product installed on one other computer which is at my home, unfortunately, I am away from home because of Covid and cannot return at this time.

Any advice or guidance woudl be greatly appreciated.

Show us a screen capture of your editing changes. Please make sure you have selected the Image Format as JPG and not as "Original".

You can contact Adobe to have them de-activate LR 6 on other computers.

dj-paige is also asking to see your options in the Export dialog.

Do you  have "JPG" selected in the [File Settings] panel?

It was set to orginal.  When I changed it to jpeg, the export feature worked.  Thanks very much.  How do I go about deactivating the software on another device from a distance?

How do I go about deactivating

Goto https://account.adobe.com

Goto Plans > My Plans > Manage Plan > Activated Devices

Where you can deactivate other installs on other computers.

(Deactivating does not delete or un-install the software. You can have multiple installs but only two activated)

Thank you for responding.  I clicked on "My plans," but did not see an option for "manage plan" or "activate device."  Below is the screen capture.
