Do not post your log inside a message but, instead, ZIP IT and ATTACH IT to a file, because we need to look the actual log, not something that might have changed by the forum software as it was a post.
Also, be sure you enabled Logging in the Troubleshooting section of the GSX Settings, because the normal panic log is not detailed enough to understand the problem, so you need to enabled logging, and post your Couatl.LOG file, not the Couatl.ERR file, which won't be used anymore, as soon you enable logging.
