This is the common problem faced by many these days.
For all the returns you filed,check from xml status if the xml is rejected or not. If it is rejected, then you have to upload it again. As No Record is the only answer for ST3 status.

There definitely is some problem with the ACES site - the uploading of filed returns takes a number of months. The uploading in ACES is still done manually in the Department and hence the backlog.
However, now the ST-3 Returns for the period July to September 2012 is available at the site. I printed a filed return just yesterday.
