I'll try to be as detailed as possible. So basically my PC broke down and I got a technician to transfer all my files to a new computer. He did so by moving the hard drive from one computer to the other. The new computer has two hard drives now, the new one being C: and my old one being renamed E:. Now the old hard drive still has all my files, steam, spiral knight everything (I use Spiral knights with steam btw). I opened Steam and updated everything but now when I try to run Spiral knights, it doesn't load even though it said everything updated correctly. If I click it again it says the app is already running but when I open task manager there is no Spiral Knights running. Do I need to reinstall Spiral Knights or Steam? If so how would I handle it with the two hard drives (do i need to delete it from the old hard drive?) I'm using Windows 7. The old hard drive used to run on Windows XP.
