After clean windows %temp% task progress change to 100.000%
and task status show 'Computation Error'

The bad news is that your model has crashed. Unless you have a backup made before the crash there is nothing to do but move on. I see on the Serer Status page that there are 12,000+ Hadam3p_eu models available. So reset your model preferences to except these (if it is not done already) and make sure that allow new tasks is new work.
