Forget the debugging. It doesn't help any way.
Have you run a virus scan lately? It may be a shot in the dark but someone did have one cause a problem with Hoster.
To look for the folder open Windows Explorer, click on Tools/ Folder Options. Go to View tab. Check the boxes for "Display the contents of system folders" and "Show Hidden Files and Folders" then uncheck "Hide extensions of known file types" and "Hide protected operating system files". The last one will ask you if you are sure - answer yes.
Click apply and OK to close this. Now Windows Explorer will show you everything on your hard drive.
Follow the path in the error message and see what is there. Do me a favor and write down the exact path listed in the error message character for character so I can try to trace this on my computer.
