Ugh... if I knew I'd have so much trouble upgrading to a 4Gig SDHC I don't know if I would've done it.
But anyway, I did get a SDHC for Christmas. I have an Asus A696, and after a bit of work got the driver upgraded to properly read the SDHC. Of course, iGo stops working.

After a lot of trial and error, I read everything through very clearly in the first post, and still couldn't figure out what to do!
Well, finally, after some trial and error I found that installing the June 18 update, and then using the Aug 13 patch on top of that will get me past the HardwareIDError message.
However, while I got past the error, I'm still having trouble. When the program starts up the screen is sorta "split" Part of the right side of the splash screen is on the left, and part of the left is on the right. Plus I have a large black area at the bottom.
I'm wondering if this is because I have a QVGA screen? Does the newer iGO only work on full VGA screens?
I'm using MioMap right now, but I'd prefer iGo if I can get it working.
Thanks for any input anyone can shed.
