CS Cart Errors Need Fixed ASAP

The final goal is to install a giftcard company's API code into this shopping cart (cs-cart) along with adding SSL security. But first the following issues are priority. This is an email I received from CS-Cart along with the problems. CS-Cart 2.2.1 Porfessional has been installed on your server successfully. We have noticed the following issues: 1. SSL certificate is not installed on your server, so please do not enable the following settings on the Settings page in the admin panel of your CS-Cart: * Enable secure connection in checkout (SSL certificate is required to be installed on your server) * Enable secure connection in administration area (SSL certificate is required to be installed on your server) * Enable secure connection for the authentication and profile pages (SSL certificate is required to be installed on your server) 2. Mailer error. We got the following error when the message was sent by the store: Message could not be sent. Mailer Error: Could not instantiate mail function. Please contact you server administrator to resolve the problem. You can access the E-mails settings in the 'E-mails' section (click on the 'Settings' link in the 'Administration' box in the admin panel). Please check the installation and let us know the result. 3. The Font on the Register Page cannot be read. 4. Can we change the words "Orders" to "My Orders". 5. When trying to register, I got an error message that said could not initiate mail function. 6. Error message appears when I try to send my information on the contact page Serious inquiries only. NEED DONE ASAP 24-48 Hours. I will send access to selected bidder. I have attached a jpg of the site's front-end.
