Just upgraded 3 gateways from 8.1.34 to 8.3.4. One gateway upgraded no problem. All modules activated. 2 other gateways, the only a few activated and most are in trial mode, vision module, sql bridge, Allen Bradley driver, reporting, symbol factory, OPC-UA, Logix driver …  
Tried the re-activate button on the license page, but no change.  
Anyone have this issue or know how to get things working again or do I just need to call tech support?  
Tks

Any chance your gateways can’t access our licensing servers? Could you try an offline unactivation then an offline activation, if that doesn’t help reach out to support.
