It may be a problem, but try running this anyway, go to the start menu and type cmd and then right click on the icon and run as administrator, once you have opened command prompt type sfc /scannow and hit enter, this will start a scan of your system files and it will try to repair any corrupt ones, if it finds any restart the computer and see if you can create a restore point.
If that fails you may want to try and enable the send feedback option again and if doesn't help then you could try a Repair Install or you could just upgrade to one of the newer builds, allot of people are still saying that build 7048 has been the best so far.
