Admittedly I purchased my Line 6 RiffWorks Guitar Port almost 9 years ago.  I recently loaded the Line 6 software via CD onto my desktop.  The CD says "Line 6 Guitar Port Version 2.5 CD Rev.K" at the top but then says "Sonoma Wireworks, RiffWorks version 1.0" on the right hand side of the CD. I can open guitar port and Riffworks, however Riffworks fails to activate and thus i cant record anything (the only reason I purchased this device).  I've been reading many posts that all say to try something different.  It doesnt appear anyone but a Line 6 representative can give me an absolute answer.  Can someone from Line 6 please explain how I can activate this software and potentially upgrade to the latest version.  Thanks.
