Have been using Xplane 11 for over a year now, having had several successful updates. Today I get the following error when attempting to update my current version:
"There was a problem updating Xplane. The technical problem was: unable to open .zip file. It may be missing or damaged"
Current version is Xplane 11.21r2 (build 112101 64-bit) running on Win10 Home, build 17134.228
