Error: Current license file does not support the EP2C5Q208C8 device

[Altera_Forum]

Just installed 10.1 Web Edition, compiled, and got this message. 

 Why? I thought Cyclones were fully supported in Web Edition?  Quartus identifies itself as Version 10.1 Build 153 11/29/2010 SJ Web Edition with no Service Pack Installed.

All Cyclones are. Quartus II 10.1 is just buggy. I can't get mine to compile. It just errors saying "Selected Feature of TimeQuest timing analyzer is not available with my current license." Too bad I uninstalled ver 8.1 because that was working FINE.

I just experienced a similar problem; Quartus had completed a couple of builds successfully, then, without shutting it down, it decided it couldn't find a licence (licence in use). 

 Re-start of Quartus didn't fix. Licence is permanent, so not expired. No-one else is using it. Couldn't see any obvious Quartus processes in Task Manager.  Re-boot of PC fixed the problem, so I suspect Quartus got a little 'confused' about the state of its licence.

When I try to compile .bdf file in project I get messages : 

"Error: Selected feature of TimeQuest Timing Analyzer is not available with your current license, or license does not exist" I use Quartus II Version 10.1 build 153 11/29/2010 SJ Web Edition  Then I installed it on another PC and it works normal. The OS is the same. Difference only in RAM.  Can I have this problem becouse I use only 512 RAM?
