Fast and Easy Checkout is not displaying

[picandnix]

This is so frustrating... I decided to install the css js loader and the fast and easy checkout files on my live hosting server until I figure out how to get my site working properly on the wamp server. I uploaded the css js loader files first, I think it installed successfully as I didn't receive any errors and I noticed some of the text on the pages changed to ariel font, and it looks more sharp. I don't know if the Java makes this happen.
I then uploaded all the fast and easy checkout files - I forgot to mention... I merged all the files first for both installs before I uploaded the files to the server.
Can you clarify when you merge a file, you copy the difference over to the existing file on the server?? I didn't copy over the blank spaces, just the text. Did I do this correct??

You have to merge (copy over) the coding that is needed/missing for your files. But not ALL the code, you need to copy bits that don't overwrite what your files need. This sounds obvious but it's a tricky one (trial n error for me til I no longer got errors or blank pages...but I did it in wamp first as it took me MANY evenings to suss it one file at a time).
Numinix offer a commercial service for installing, it may save you the nightmares? It's hard to advise without specific errors or even which file is giving you errors or blank pages.
Are you/which template are you using?

Can you shed some light on exactly what errors you are getting in cache? Also a link to site, PM me if you'd rather.
