Just recently I had to re-install my Operating System. I decided this would be a good time to start my Skyrim over from scratch and set everything up exactly how I wanted it this time. I have the newest version of Mod Organizer installed (1.2.17) on J: which is a dedicated 150GB 10,000rpm drive just for Mod Organizer and my mods. My Skyrim is installed on my games drive D: I have a SSD as my system drive, so I prefer to keep only the OS and required files on C: I use Chromium 64 bit installed as my user, as is Mod Organizer. When I click on a file in Chromium to download a mod from Nexus, the first file downloads with no problem. The problem happens if there is at least 1 file already downloading and I try to download another, this is when it all falls apart. First I get a message saying "failed to communicate with running instance". When I click OK, Mod Organizer freezes (Not Responding in the title bar) for a good 10-15 seconds and then it shows it downloaded the file. It also does the "Not Responding in the title bar" for almost every action I attempt in MO, like enabling a small mode like "Live Another Life" which froze it for at least 10 seconds as it enabled. I have moved all my files to another drive and re-installed MO fresh and tried doing everything again and it still does it. So re-installing MO didn't help. I checked the NTFS permissions and the security settings for the drive and folders, all is setup ok. Before I reinstalled my OS, I was using 1.2.15 and it didn't have these issues. So I am at a loss as to what it could be. Could it be something with my new install? Something with the new version? Any ideas would be greatly appreciated.
