Yes. If the same LiberKey (in your folder managed by dropbox) is running at the same time on multiple computers, conflicts can occur during data writing.
Check in your folder
\LiberKeyTools\LiberKeyMenu\data\Menu you should have files, created by dropbox, like:
recent (
Your_dropbox_name conflicted copy
timestamp).xml
You can delete these files then re-launch your LiberKey.
