Hello Reinaldo, thanks for contacting us!
We have temporarily disabled Proteus support on SnapEDA due to circumstances beyond our control. We are working to re-introduce it over the next few weeks and will share updates here: https://www.snapeda.com/questions/question/an-update-on-proteus-support/.
Thank you for your patience as we get Proteus support re-introduced!
