I have deleted all log files and tried to move all files except 2 vmdk files again (using Winscp) by owerwriting the old files. ESXi asked me whether I have moved or made a copy so this time I choosed the copy option as my answer. When I power up the VM it still does not work.
I am out of ideas and thinking that I might try another option like Trilead's VM Explorer and start over again.
