CreLoaded fix-up

I have a CRELoaded site close to fully working but I need some critcial fixes: 1) From my main page when I click on a product (Add to cart) I get a 404 error saying 'No document found on server'. This was working a few days ago and I know the product does exist on the server. Accessing the product any other way seems to work fine. 2) When sending an email from my Contact Us page, the site says the email was sent to the Store Owner (me) but I do not receive the email. No email is actually sent. 3) I get a 'FATAL ERROR: register_globals is disabled in [login to view URL], please enable it!' error when trying to access me Admin...I need to refresh to get it to work. I check my [login to view URL] files and register_globals is ON. I did notice that register-global for the Master Value is ON, but for the local value is OFF. I'm not sure how to fix this and need this done for me. 4) I recently purchased an SSL certificate and need it enabled to work for pages where the customer is entering personal information (on checkout) and paying with a credit card. I do not want SSL certificate for just browsing products.
