7010 & 7011 Patch Install Problem

When trying to install the 7010 or 7011 patch on my test system, it will install the patch and says it was completed, but after i try to start SDP again, it hangs and "starting applicaiton layer". Anyone have thoughts on this. it's happened to me on but my production box, and test box.
Thanks!
