We have recently discovered that Cobalt fixture library update version 15.4.0 onwards (Oct 2019) may not be usable on XP Congo family consoles as they have grown too large for these consoles and the Import Template Wizard may time out and cause a crash.
XP consoles can be distinguished as they have one (1) RJ45 network jack.
If you have an XP console and need fixtures from a newer library, we recommend using a Windows 7 console, or Cobalt ETCnomad (at the same version as on your XP console) on a PC to import the templates into your ASC showfile.
Once imported into a showfile it may be patched and repatched on any Congo and Cobalt family console.
