Accidentally withdrawing an RPI request - help with next steps

I have accidentally withdrawn an RPI request whilst trying to correct an error. 

I received an automatic email from EMA asking to clarify if this withdrawal was a mistake and I have replied as directed to say that it WAS a mistake. 

I am however unsure what the next steps are, since without the RPI submission being available again to edit I cannot progress my application. Does anyone have experience as to how the submission is reinstated for editing and submission, and how long this takes typically?

Many thanks.

Your request for RPI has been approved yesterday. When a withdrawal is requested, the system automatically sends an acknowledgment, asking the applicant to inform us if this has been a mistake. In such cases, the procedure will not be closed but will be progressed normally in the system.
