Issues Building Intel Nios V/g core

I thought it might be a license issue but I was confused as I have a valid license which I've used to build Nios V/g in Quartus Standard, however I've realised the Flexlm License Daemon we were using was out of date, and updating it to a newer version has resolved my issue.

I'm surprised Quartus doesn't give a warning about this, or even that Quartus opens if I was using an unsupported version, but at least I've fixed it now.

Thank you for your reply,

Samuel
