Hello Shahiru and welcome to the forums.
I would hazard a guess that you will need to deauthorise, uninstall and then reinstall/reauthorise TR5 in order to gain access to the plugins you have deleted.
As this is a user-to-user forum and not direct to IKM support, in case no one else chimes in here with advice or a solution 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, 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.
