This worked, thanks.

Unfortunately, none of that seems to have worked (there wasn't even a windows explorer task up in Task Manager) Thanks for trying though.

After experiencing the "checking for updates" bug a few others have noticed, I decided to just straight up delete my KSP 0.90 folder and download 1.0. But the Launcher refuses to be deleted, claiming it is running somewhere on the computer. I checked the processes in task manager and there is nothing KSP related running there. Any ideas how to get around this?

Thanks for the suggestions everyone.

I have a spaceplane, the design of which works for in atmosphere flights. However, once I added a pair of symmetrical boosters to allow it to get out of the atmosphere, it began noticeably veering off when it starts moving on the runway. It did this slightly before the boosters were added, but is now much worse and makes taking off impossible. Here is the ship in question. Any help would be appreciated.
