nios2 eval license

Thanks. What makes the problem a bit odd is that the other megafunctions in the

library seem to instance properly. It's just some of the cores that are "core" (pun

intended) to implementing a NIOS2 design on a BeMicro or DE0-Nano design

seem to be a harder to re-download.

I believe the problem I'm running into - which is adding an accelator to the BeMicroSDK

design - is probably due to an "old" NIOS2 license hiding somewhere in my design

folders. Had hoped to just re-download a fresh time-limited license to clear

things out :)
