From you log, I found vmdks(Virtuelle Festplatte-00000x.vmdk) belongs to snapshots are still in your VM bundle(Win 7 x32 Enterprise.vmwarevm). Try following:
1. Delete 'Virtuelle Festplatte-000001.vmdk', 'Virtuelle Festplatte-000002.vmdk' and 'Virtuelle Festplatte-000003.vmdk';
2. Open 'Win 7 x32 Enterprise.vmx' with editor, then change
scsi0:0.fileName = "Virtuelle Festplatte-000003.vmdk" To scsi0:0.fileName = "Virtuelle Festplatte.vmdk"
After this, I think your VM could be powered on normally.
