How long did you let it run? And also make sure that your recovery is up to date... And also make sure that the installation zip file isn't corrupted, it it's corrupted, it'll get stuck in the same fashion just re-download the rom and try again, and if still it remains the same, start from scratch (flash the stock firmware, then unlock bootloader and try installing this rom...
Edit: Are you using a keyboard and mouse in the recovery or is the cursor persistent at all times...
