Mca prescrutiny error

Dear Freinds,

While uploading a din form, I have come across following error again & agian and not able to proceed as one din form is pending for upload .... even I subsequently uploaded the form and paid the fees still getting error message below: 

SRN must be of pattern [1 upper case alphabet followed by 8 digits] 

Now my query is,

How to clear the incomplete DIn upload from "Prescrutiny Form" so that i can "prescrutiny " other forms>?
