Can't get Laputa to see installed books

[usn.mustanger]

Does anyone have Laputa II successfully working on their DInc? I have the latest version installed (2.2), and I've installed a few titles, but there are two problems: first, after installing a Laputa title, there is a button that says "Open Laputa". When I click it, I get an error dialog saying that Laputa is not installed, and offers to take me to the Market. (I can assure you that Laputa is indeed installed, and it runs).
Second, when I open Laputa by clicking it's app icon, it runs just fine, but none of the titles I just installed show up, and there doesn't seem to be an easy way to add books that you've already uploaded to your DInc.
The title installation packages install the book files to a subdirectory on /sdcard, and using Astro, I can see that they are all there. Laputa just doesn't see them. I'm wondering if this is an anomaly due to the internal storage on the DInc.
Sure would love to get this working.
Can someone else try? Laputa and many titles are free on the market.
TIA for any help!
