Weird Problem - Myth II Wont Start Up

[Rico-suave Bastard]

When I try to start Myth 2 up it pops up and tells me that it is missing necessary files and to insert my cd (which is already in and i shouldnt need with 1.5) or do a full install (which i already did, reinstalling 4-5 times already). I was just wondering if anyone has encountered this problem before and if there is anyway they can help me out with it. I have an iMac 400mhz and a PC, and it gives me the same message. I can send you my mythlog file if you want to take a look. Some help would be appreciated, thank you in advanced.

It sounds like your CD might be scratched, and its not able to read some of the files it needs. Post your myth log here, so we can take a look at it and see if it is of any help in debugging your problem.
