### CosmoMC: Why this error?

I followed the instructions in CosmoMC Readme and the compilation seemed successful, but an error occurs when running cosmomc. Thanks for any suggestions.

Hi,

it seems like you do not have the WMAP3 data installed properly.

Run the WMAP likelihood test program. If that works, make sure you modified the path for the data files (as instructed in the CosmoMC readme) before compiling for use with CosmoMC. If the test program doesn't work, the problem is with your WMAP installation.

Thanks!
My mistake is that after I modified the file "WMAP_3yr_options.f90" as instructed in CosmoMC readme, I didn't run "make clean" and just ran "make".
