So i did it… i had to kill my vmplayer and after a computer reboot could not start my vm… ok this is my working vm… and atually i relay on it… and i really didnt want to reinstall it… and i really got a bit afraid, that today i just reinstall the vm, and acrually cant work…
so the error was:
Cannot open the disk ‘
.vmdk’ or one of the snapshot disks it depends on.
Reason: Failed to lock the file.
So after reading the first google it, i installed an unlocker, to unlock all the files… host os is windows7, so actually i thought, this can be possible… but actually there was no lock on the files… after googling a little more i found this. So i deleted all the *.lck folders and tada: every thing is back to normal 🙂 i think 😛
