I just used a small piece of software from Adobe to clean up the left over part of Adobe Photoshop CS3 trial version to go for a official one. I install successfully and restart my PC but Explorer won't start until I open a new task manually in Task Manager. I don't why, I think that I might damage the Registry while try to clean up the left behind part of PS CS3. Does anybody have some idea for this kinda situation? Here is my HJT log file Thanks for you time!!
