G'day Tngan,
Given that the SRCSASRB is a pretty new card (as far as I know), it is quite likely that the drivers in DSS Lite can't run the Web GUI (even though they may be able to work with the disks).
Since the full version of DSS is newer, perhaps trying the eval version will work better. At least you will know it is not the card.

To ensure you don't have an issue with the card, you could try booting with a LiveCD such as UBCD or UBCD4Win (not sure if they support this card though).
