I removed ESS Version 3 with the Uninstall and then deleted all folders under the Program Files, Documents and Setting, All users and under my folder and then rebooted. I then installed ESS 4 without any problems, it updates and seems to be fine, but when I reboot my system it fails to boot. It gets in a reboot loop. I have to pick last known good setup... to get it to boot. Then ESS 4's Startup Windows stays open and it does not run. After about 10 minutes I get a communication error with the kernal and it shuts down. It has been two days and no help from Eset. Does anyone out there have any ideas?
