cannot install linux bf2 :(

[Jonathan]

Hi 
I must be doing something wrong :(

Cannot get the file to install 
Run  ./bf2-linuxded-1.1.2475.0-installer.sh

Verifying archive integrity...Error in MD5 checksums:
0d901f75affcd6579c6458a1e8b061db is different from
a915617e4852767c831d26800a6660da


Is there away to force it to run?
I had the same problem with the first release of bf2 so I downloaded the
.zip the unzipped it & ran it ok
