be patient. put it by a window so it gets lots of light and gets cooler temps at night. I had 2 paphs that refused to bloom for over 2 years since I bought them... then when I least expected, they bloomed.
It'll bloom, just keep watering it about once a week and give it lots of light. good luck.
I agree with all of the above.... and yes Be Patient ...the most important is that it has good roots & leaves.... once 'super healthy' it will flower...
