Okay, elaborated steps:
In ROM manager -> Flash ClockWorkMod Recovery, select the 1st ROM and let it download.
2.) Got to sdcard/clockworkmod/download/download.clockworkmod/recoveries, you'll find the downloaded recovery from Step 1 there.
3.) Move the file from Step 1 to this location and rename it so that it has same name as the downloaded one.
4.) Click Flash ClockWorkMod Recovery Again.
Done.
