Render Manager makes 3ds freeze and never start

Hello this is a new issue we have. We have loaded render manager on two seperate computers identical. Both use 3ds max vray anima forest pack railclone. These two computers will be used as nodes. One of them works fine.

On the other machine when i activate render mode in render manager and it takes on a task, it fails to load 3ds max (it says it took more than 5 minutes) and then if i try to open max by itself to work it just doesnt open. I have tried to uninstall everything 3ds max related, and reinstall everything. 3ds max works fine, we have both vray and corona on this machine, opens normaly. As soon as i install render manager and try to give it a job, i cant open max anymore.

Any solutions?
