You bet - so, under the Publish options in the backstage, you should be able to export the form files. Export the files to a folder and close the form. In the source files, look for the QdabraRules DLL (the full name will vary depending on what version you injected, but the file extension is "dll"). Then, open manifest.xsf in a text editor and search for the file name (or just on .dll) - you'll find something like this:
<xsf:file name="Qdabra.Tools.RulesLibrary.dll">
<xsf:fileProperties>
<xsf:property name="fileType" type="string" value="rootAssembly"></xsf:property>
</xsf:fileProperties>
</xsf:file>
Delete the entire file node. Save the manifest. Then right click on it and select design to see if the form opens back up in design mode - if it doesn't the error details should have more info about what's going on - it is easy to make a mistake, so if you have trouble let me know & I'll happily give you a hand. Once you have it open in design mode, File > Save As packs it back up into an XSN.
