I have been making a substance fo a few hours in Substance Designer. The program seem to stop refreshing the 3d view. I restarted my app and I now get the error Application is too old to open URL Current application manages format version "126.96.36.199005" instead of "188.8.131.52102" Can someone please help me firgure this out?
I am glad you were able to solve this issue! It appears two different versions of Substance 3D Designer were started back to back, one of which did not support the latest updates to the Substance 3D file format (SBS), brought along by the latest version 11.2.0.
The steps you took cleared up the possible confusions and, indeed, the latest version is available on the My Licenses section of the Substance3d.com website. The Substance Launcher does not fully support versions released after June 21st 2021.
