The error you've got might be a corrupted SDM file. Try downloading and re-install SDM (use version 2.5). I would suggest using CCP which is the newer and more current router GUI.
Just make a quick Google search on the Java version I've suggested. It's not that hard to find it. Make sure you've removed the current one first and install the old version.
