使用Xamarin Enterprise帐户登录Xamarin Studio和Visual Studio时出错

Question

在Xamarin自动签名后，我无法重新登录我的Visual Studio Xamarin帐户。我收到以下错误消息：

System.FormatException: One of the identified items was in an invalid
format. at
Xamarin.Components.Ide.Activation.ActivationService.GetErrorWorkflow(LicenseSyncResult[] results, Boolean ignoreSyncErrors) at
Xamarin.Components.Ide.Activation.ActivationService.d__61.MoveNext() at
Xamarin.Components.Ide.Activation.ActivationDialog.DisplayWorkflowStep(ActivationWorkflowStep step) at
Xamarin.Components.Ide.Activation.ActivationDialog.<>c__DisplayClass30_0.b__0(Task t)

请帮助，谢谢。
