Adobe CC not recognising active subscription on old mac

[Claire28497188gyhh]

Everything was working fine. Old mac, old system and old CC version (2017 indesign, photoshop, and illustrator). This morning I restarted the mac and suddenly it will not recognise that I have a paid up subscription. Goes to the Renew your subscription page. 

In the list of apps available in Adobe Creative Cloud panel it list the apps as Open but will not let me open them. 

Cannot open them via browser either as it's too old and not supported. Cannot update mac its as high as it will go.

if that fails, proceed to these steps - https://helpx.adobe.com/enterprise/kb/resolve-trial-and-license-expired-errors.html

if that fails, https://helpx.adobe.com/download-install/kb/adobe-license-issues-keychain-credential-mgr.html

if those all fail, change your cc language.  eg, try international english

if that fails, change the install location
