Can't help you with your problem but I'm thinking of buying a Thrive what do you think of it ?
What attracted me to the Thrive were the full-sized ports (USB, SD, HDMI). I bought a 320GB portable (USB-powered) Toshiba hard drive ($35) and it works fine on the Thrive, as does the full-sized 32GB SD card ($50). You can use up to a 128GB SD card on it.
Although I like the size (7") of my Archos 70, and it has a 250GB HDD built in, which is nice for holding a lot of music and video files, it doesn't have a rear camera nor GPS, both of which the Thrive has. Plus the Thrive runs Android 3.1 and the A70 is limited to 2.2.
I've read comments about the Thrive's display not being as bright as some others, but it's plenty bright for me -- brighter than the Archos. On battery, I'll be using it dimmed anyway. Because of the full-sized ports, it is a little thicker and heavier than other 10" tablets, but we are talking about fractions of an inch and ounces here; doesn't bother me. You want something light and easy to carry, you get a 7" tablet, not a 10".
