Never good to hear that a customer has lost data. I can't guess from your description what would cause the workspace to be wiped, but I can say that I have not heard of other calls like this.
I hear your frustration, but I have no advice to offer so not sure my words are any help.
I'm not in the position to off your any VAR recommendations, but I would be interested in addressing the problem if more concrete information could be provided for us to investigate.
I gather you were unable to capture any logs to place a call?
