Hi Greasefire and welcome to the forum.
Ok, few things to make sure of/do:
1) Try rebooting your computer. This can fix all sorts of problems.
2) De-authorise and reauthorise your AT5CS app via the IK Product Manager
3) In the Custom Shop app, click on your Username then Restore My Purchases
If that still doesn't work, as this is a user-to-user forum and not direct to IKM support, the best thing to do is check the FAQs, via
https://www.ikmultimedia.com/contact-su ... ck=QUICKSWIf these do not resolve the issue, there is a link to the Technical Support form at the top of the Search FAQs page, for direct help from Official IK Support. They endeavour to reply within 2 working days, but obviously considering the current situation things may take longer than usual.
And, to help others who run into a similar problem, please let us know what you did to resolve the issues, but without directly quoting any correspondence from official support.
