Any ideas on why I receive an error below when running the run_miner.sh on ubuntu 12.04 (the miner is the latest beta2 version from heavycoinpool.com).

suky@ubuntu:~$ cd Desktop
suky@ubuntu:~/Desktop$ ./run_miner.sh
bash: ./run_miner.sh: /bin/bash^M: bad interpreter: No such file or directory
suky@ubuntu:~/Desktop$ ls -la
