Invalid Hp learner id

[A.Saini]

Hi All,

Today, I had my HP0-M39 Exam. But I could not give it as the prometric center I applied is saying this learner id invalid.

I do not understand the reason why it's happening.
I am able to login to my hp account and that learner id ("PL*******" where *-numeric value) is visible.

But the prometric center software is saying this learner id "INVALID".

Please let me know what should I do?
Should I create a new learner id or do something else? But in any case I want to give the Exam as soon as possible.

Please help me..
