Can you access C:\Program Files\KingsIsle Entertainment\Wizard101 If so I know of the following logs: .\PatchClient\BankA\WizardLauncher.log.txt .\PatchClient\BankB\WizardLauncher.log.txt .\Bin\Capabilities.log .\Bin\WizardClient.log
It may be found at ProgramData on Vista which is a hidden system folder. My thought is that permissions on one of those got messed with, or the file got corrupted. Did W101 crash? Did your computer? Hopefully it's not the worst thing, which is that your HDD is dieing.
