Vray 7 locks Max up when trying to render or populate material editor

[spikeadelic]

Updated to VRay 7 and still not rendering as it 'locks up' Max also does it when trying to populate the material editor, standard or slate, same in Max 2023-24.
All licences are running and OK, all the right stuff is in the Task Manager, so .................. ?
Last version VRay 6 runs fine even after re-installing over 7 back to 6 ??

Sounds like a license server issue. Try the following:
1. Uninstall the Chaos license server and remove any remaining files from this folder: C:\Program Files\Common Files\ChaosGroup\ssl
2. Download and install the latest Chaos License Server
3. Go to the license server page (http://localhost:30304) and enable Online Licensing
4. Open 3ds Max and try again

Just 'solved' it by loading an existing project from Max 2023 done in VRay 6, it took a while but it did populate the material editor and then render, with a bit of hesitation.
Tried a new scene in Max 2024 and VRay 7 seems to work now.
It seems it just needed some persuasion.
