Will my Plugins/Themes stop working after my membership expires or after a certain time?

Absoultely not, we don't alter the code to stop you using the items after your membership expires and you will be able to continue use your plugins and themes even after the membership expires. But future downloads and updates will not be available unless you have purchase an individual theme or plugin without membership or renew your membership but your existing installed plugin or theme will continue to work at there current versions.
