I have finally solved the problem.
The first time I tried to install the Clockworkmod, there was a hic up in my wifi and I guess it corrupted the recovery. When the next time I tried to install it, Rom Manager isnstalled the same corrupted version from the cache. I deleted the cache via settings in Rom Manager, and once again installed the Clockworkmod. This time it downloaded a fresh copy and flashed it successfuly.
Hope this will be helpful to others with the same problem.
