Form 10BD Error

Hello

I have submitted the Form 10BD on 5th, then i revised one donation type from the donation. Now i am trying to revise again one of them. While revising the form there is an option to "Export 10BE's generated to CSV", the blank file is getting downloded after clicking there, but as i revised last time, all entries which we have submitted gets into csv when i clicked on that option. But this time blank file is getting downloaded, because of this we cannot revise Form 10BD again, the error shows "Acknowledgement number does not match with submitted 10BE ARN". 

Kindly help me with this because the last day to file 10BD is 30th June.

Thanks
