Hi Zakia. Totally understandable on the plugin change.
Odd that the image on the slider would disappear; is that slider a built-in feature of Responsive, or is this a separate plugin? If so, what's the plugin? That is the type of issue that - if you're a PRO user - our support team at the http://tri.be/support/forums page could help you out with in greater depth than I can here at dot-org.
If you pay and reinstall it, while there may be integration issues on first installation, we can do our best to help you get that sorted and will certainly give you a full refund if we're unable to get that sorted due to some limitation on our plugin's end.
What aspect of the installation would you need help with? While we don't have phone-based support, we do have a new user primer that covers the initial setup (http://tri.be/new-user-primers/). And we are always available via email, pro /a/ tri.be, to answer questions you have.
That help? Let me know if not.
