Hello,I am having a problem running the IDE on my Windows 8.1 64 bit laptop. I installed IDE 1.6.4 and when I launch the IDE the splash screen shows up, and at the bottom the following messages are displayed in order;Loading configurations...Initializing packages...Preparing boards...Starting...Then the splash screen goes away and the IDE never comes up. There are no error messages associated with this problem and I even tried the previous version of the IDE with the same results. I tried running the IDE in Windows 7 compatibility mode and the result was the same. Edit: Ok, I found another thread for the 1.6.3 IDE and it said to remove the arduino I5 folder from the user/appdat/roaming directory. When I do that and the IDE does load. But when I try loading a sketch, there are errors and the sketch/example options in the file pull down go away. When I close the IDE and try to re-open, I'm back to the original issue.Edit2: Ok, I narrowed the problem down to a bad folder in my sketch folder. Once I eliminated the offending folder all works fine now. Sorry about troubling you with this issue.Thank you in advance for any assistance you can offer.
