No tables found in database (no replies)

I was using wamp for a while with no problem.
few days ago i wanted to create a new data base and after clicking create new data base i got this messge " No tables found in database " and asked me to create table manually.
I uninstalled wamp and installed it again. same problem. tried another browser same problem.
thinking maybe windows has problem changed it again same message. tried another version no chance.
I don't know what happened which in fresh windows and xampp installation still same problem which i didn't have before.

Please let me know what happened.

Thanks
