Bangalore Water Supply & Sewerage Board [Bwssb] — paid the exam fees but while downloading the application an error message pops up stating pay the exam fees.

I have applied for the post of bwssb Assistant Engineer post. I have paid the exam fees amounting Rs.608/- on[protected]. My application number is AES10002645. I am not getting why this is happening. I am seeing lot of people getting similar problem. I think bwssb board should solve this problem fastly.
