For the past few days, I have been unable to open my QuickBooks files because of an error. When trying to open them, I get a message saying "Cannot open file. Error 106."I know the error isn't my computer's fault so I called customer service and tried calling their number. The phone was answered by someone with enough patience to help me fix the issue.
