I found the issue. I downloaded and ran this program, and it fixed everything. http://www.softpedia.com/get/Others/Miscellaneous/Jarfix.shtml

The funny thing is that this started after I ran dskchk... I thOught disk check was supposed to FIX problems, not cause them...

Yeah, I'm using the jar file, however when I try the exe, an error message gives me this: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.UnauthorizedAccessException: Access to the path 'C:\Users\<USERNAME>\AppData\Roaming\.techniclauncher\technic-launcher.jar' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at TechnicLauncher.Form1.DownloadStringCompleted(Object sender, DownloadStringCompletedEventArgs e) ************** Loaded Assemblies ************** mscorlib Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5456 (Win7SP1GDR.050727-5400) CodeBase: file:///C:/Windows/Microsoft.NET/Framework64/v2.0.50727/mscorlib.dll ---------------------------------------- TechnicLauncher Assembly Version: 1.0.1.0 Win32 Version: 1.0.1.0 CodeBase: file:///D:/My%20Documents/Downloads/TechnicLauncher.exe ---------------------------------------- System.Windows.Forms Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5460 (Win7SP1GDR.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll ---------------------------------------- System Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5456 (Win7SP1GDR.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System/2.0.0.0__b77a5c561934e089/System.dll ---------------------------------------- System.Drawing Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5462 (Win7SP1GDR.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System.Drawing/2.0.0.0__b03f5f7f11d50a3a/System.Drawing.dll
