Hmm. Did you completly uninstall the previous version before the 2.9.8 install?
I run the uninstall, then use the Find to search for anything "limew" to get rid of the old preferences, installer, and download. To really start fresh, I delete the "incomplete" folder, the old err.txt, the out.txt, but leave the Shared folder as it is.

Doesn't cmd-clicking the search tab for the file you want to get bring up the option to "Repeat search"? That should start the download if the same file can be found. The Could not download message replaces the old requery message.
