i was doing online ST registration of a person. But as i submited ST-1 form an error appeared "Your Request Can not be Processed, Please contact the System Administrator". i tried in many ways to register it online using different browsers & their versions since last 4-5 days but all the time same problem was faced. I know i have the option of applying manually but can i re-register the person in ACES & apply for registration from the beginning. If it can be done then will i be alloted st regn no. as SD001 or SD002.
