Error on running VMWare: Unable to build Kernel Module

Hello,
I installed VM player version 3.1. All the installation process went well. Unfortunately, when I’m trying to run VMWare, I received this error. On checking the log file, I final line of the log file stated that ‘Failed to compile module vmmon!
Please help me on this! I need to fix this issue immediately as I have deadlines to meet.

Error:
“Unable to build kernel module.
See log file /tmp/vmware-root/setup-3759.log for details.”
Thanks,
Tracy
