Dynamics CRM Early Bound Generator Error (XRMToolBox)

Question

We are using XrmToolBox to support early bound (with early bound generattor).

From one day to the other the early bound generator doesn't work anymore.

I got this log from the ui. What's the problem or where can I find the entire log?
