Help with rar speed devils and cannon spike

[Dflynn]

I am having a little trouble with speed devils, and Cannon Spike. I have downloaded all the .rar file, but when I try to open the rar it tells me that it cannot find the archive. When I go into winrar, and select the file and choose repair it says that it found the .cdi, and has repaired the archive. I then try to extract the files, and no go. same error. I downloaded win-sfv32, and it checked the files, and said everything was fine with the files. Is there anything that any of you can think of that I should try. I do not want to download the files again, as I beleive the files are fine. If anyone has had anything similar to this happen to them let me know what you had to do.
