Wol & exec binding -> power On and Off Pc

I know I asked you already alot today but I would like to ask one more thing.

After Installing the exec binding again I also installed the regex binding in order for the exec command to work.

While doing so i received an error: Failed installing 'openhab-transformation-regex': Error restarting bundles

Could you maybe take a look, maybe you already know this kind of error and know an quick solution to it.

I think because of the error described above the shutdown command is still not working

Thanks it advance.

kind regards
