Hi all – a few thoughts / questions here.
My first instinct is to say that problem isn’t WP 3.6 per se, but other issues in NextGEN 2.0 that are causing issues. We’ve updated quite a few sites to 3.6 without problems, while here on the forums we are seeing quite a few issues with NextGEN 2.0 even on WP 3.5.2 or earlier.
Can anyone here confirm that you updated to NextGEN 2.0 and know everything was working fine, and then updated to WordPress 3.6 and it then broke?
If you upgraded to 3.6 and then 2.0, it’s quite possible you would have had the same issue regardless of the 3.6 update, and we’d need to diagnose otherwise.

With that a few thoughts about solutions and troubleshooting.
*Don’t click the “uninstall” link in your backend. As with all plugins, that removes all relate files. For NG, that includes images.
The first and most direct solution: roll back to NextGEN 1.9.13 right now and wait for a more stable subsequent update of NextGEN. Here’s a rollback guide:

Second solution: We’ve introduced some fixes for numerous issues already, but are waiting to fix some more and test before pushing out a release. We decided to make the most up-to-date version available here:

You can try updating and see if that resolves your issues. If not, you can always still roll back.
Finally, as a third place to look for solutions, you might consider looking through the thread on known plugin and theme conflicts to see if any of those match the issues you are having. If they do, you could solve it be deactivating the other conflicting plugin.

Beyond that, we or you would need to troubleshoot what’s happening.
If you are going to do additional troubleshooting beyond the above, the first thing to check is plugin conflicts. Try deactivating other plugins one by one to see if there is one not playing well with NG. We already know of at least 25 various conflicts, so this is an extremely likely possibility.
For anyone above, you are also welcome submit a bug report and include your credentials and we’ll take a direct look. Given the volume, though, it may take a few days. Please include as much detail as possible about the issue.
