Hi there. I am not sure if this issue has been encountered by anyone here but i have come across a problem in the CK. I was working on an old mod fixing issues that hadn't been discovered before I published it on the Steam Workshop. Normally, my Acer monitor is connected by VGA cable to my GTX560ti and everything is cool. Tonight I decided to opt for a two screen set up for modding purposes. I ran my GTX into a different monitor via HDMI and ran my iGPU HD3000 to my usual VGA connected monitor. All was good and I was able to preview everything before putting it in the house. Job done, I decided to revert to my usual set-up. I shut the computer down, plugged in the usual bits and set to testing my mod. After I had tested my mod I continued on a single screen set-up and reloaded the CK. Once I had loaded my mod into the CK I went about editing some of the parts that I felt were wrong, but every time I tried to call up the preview screen, nothing came up. An egg timer popped up to indicate the computer was working something out but still no preview. I have tried to uninstall an re-install the CK but that didn't solve anything. I also deleted the drivers for the iGPU in case that had caused an issue. Having searched google to see if anyone else had this problem I quickly noticed a pattern of a d3d9.dll issues created after using an ENB. I have never used an ENB with this installation of Skyrim so I know that that is not the issue here. My rig is as follows - GTX560ti - 2GB Zotac 8GB Crucial Ballistix RAM 1TB HDD i5-2500k (with HD3000 iGPU) Cheap mobo. Any help or suggestions would be fantastic. Thanks for reading.
