I have 2021 using Codemeter, no issues until Saturday. Friday I did get an update and installed it and it was still working until Saturday morning. as soon as I turned on the computer Saturday windows keep asking if I give permission to codemeter, this was before I tried opening MasterCam. when I try to open mastercam the same permission window keeps coming up until it finally says I have no active license. When trying to activate the license I get the "Codemeter License server not found, Error 101". Codemeter has no license, no CmContainer and just says "Starting Codemeter, Please wait"

Gracias, Carlos. Acabo de comprar esta computadora y es solo para la cámara maestra, así que no tengo nada ni nada conectado excepto Mastercam. Hice exactamente lo que dijiste y cambié la impresora predeterminada y funcionó. Gracias de nuevo.

I just started getting the same thing, but not on the HLE. It was working great up until yesterday. My MasterCAM rep just told me to update the graphics driver and that was it, guess he had to go home for the weekend. I've done the above, updated the drivers, tried to repair the install, uninstalled and reinstalled and still nothing!
