Quickly I'll explain the problem. My old server was getting too expensive for me so I tarred and transferred all of my files, images, etc. from my old server to my new server. Everything is working great, except one script (a shopping cart script) that is giving me the following error: 

Software error:

How do I fix this problem? There is nothing wrong with the script, it must be the paths on my new server. I have to confess that I am so bad at setting paths and knowing how to make them right. Can someone help with this? The checkout.pl program 'requires' the SimHMAC file on line 430. But it is not SimHMAC's or SimLib's fault because if I comment out the line that 'requires' this file, it just gives an error for the next file in the script. This is an internal path problem on my new server, but I don't know how to remove this error. Could someone give me a little guidance along with the exact commands I need to type in order to get this working? I am desparate to get this up again asap.
Below is a url with the error I'm getting.

Edit: g0n - code tags
