If you are unable to interact with the Second Chance chest or the Portal to return to Merle's house in Malistaire's encounter, we need to see your TEST WizardClient.log file. Start by sending email@example.com an email. Use your email service to add an attachment. Find the Wizard101 TEST Folder (Default Location is C:\ProgramData (Program Files for Windows XP)\KingsIsle Entertainment\WIzard101\ ), click on Wizard101 Test folder, then open the Bin Folder and select "WizardClient.Log". After that, just hit send!
If this is too large for your email server to attach or send, then open the game folder, go to the bin folder again and locate the WizardClient.log. Right click on the log file and select Save as Zip (or similar wording - will vary depending on your specific operating system). Then, go back to your email and attach the newly zipped wizardclient.log.zip file.
