Has anyone ever encountered an authorization error when trying to download Great Circle GRIBs? I have an active HiRes subscription with Squid-Sailing. The account is active and have triple checked my login details. I can go to Squid X and download GRIBs, just not into Expedition. Hmmm.

I'm using historic NAM analyses to model an upcoming voyage. Does anyone have a way of truncating NAM analyses to a specific area? The NAM analyses are huge files and consume the memory even using the 64 bit Expedition version. Thanks.

Okay, so I want to run some routes from Annapolis to Bermuda using historical NAM analysis. The problem is the NAM files from NOAA cover the full scope of the forecast, so each file is 50MB+. I can load about 2.5 days of gribs, before I get an "Out of Memory" message from Expedition. 2.5 days of gribs is 10 files / 534MB total. I have 16 GB of RAM. One way to solve the problem would be to somehow edit the NAM files to the area of interest. I have no idea how to do that. Maybe more RAM would help, but I'm not sure that will solve the issue either. Any thoughts?

I am running an Intel Graphics with OpenGL 4.4. Will that version of OpenGL be compatible with Expedition4D?
