Need help, controllers not found.

[cojaloja]

So yesterday i started to add new controllers to the ones i already have, all went well no problems, tested with an updated show containing new controllers, everything working as it should, went back to it this morning to carry on updating new shows, nothing working, pc lead flashing as it should, controllers keep on flashing no matter what, show files and music in separate folders,  device manager says controlers not found and serial interface found, see pics and videos. working fine last two years, any help would be appreciated.











These alll had a green tick beside them yesterday.
