Search in registry getting stuck..

When i search for something in the registry with regalyser, then the search gets stuck at

My Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\SysmonLog\Log Queries

When i went up to the key in the registry ..its maybe a key with subkeys because it had a plus sign before it, but when i click the plus sign, it doesnt open the list of subkeys below it. It just stays there.... (unlike all other keys which have plus signs). maybe that is why the search is getting stuck. Whats wrong.
