Sandbox Bonus Tools

Hi there, I’ve purchased Sandbox Bonus Tools from Cadman on version 2018 of Sketchup.
Currently I’m in version 2019 but I can’t install S.B. Tools. I get an error stating License Limit Exceeded.

How can I fix this? I can’t connect with cadman… no mail or info… and sketchup.

I can’t even buy a new licence… and if I login with other account I believe I’ll loose all current plugins.

Thanks for all the help.

If you bought it in the SketchUp Extension Warehouse, contact SketchUp support directly and they should be able to help you out.
