Re: PowerCLI: Exception calling "CreateCollectorForTasks" with "1" argument(s): "The operation is not allowed in the current state."

Try restting the $creator variable at the start of each snapshot loop.

...

foreach ($vm in $myVMs) {

$snapshots = Get-Snapshot -VM $vm

    foreach ($snapShot in $snapShots){

        $creator = ""

        $VM = $snapShot.VM

        ...
