Hi rob002 and KavaKiwi (and anyone else who may be running into similar problems),
We haven't yet been able to reproduce these issues with the plugin, so we were hoping to gather some more information. Could you tell us which version of macOS you're currently running, and can you also clarify how the plugin isn't working in a little more detail? Are you unable to uninstall the plugin at all, or are you seeing that you're no longer able to use the plugin (even though it's been installed and you were able to use it previously)?
If the plugin isn't working as expected, is it not copying on the Sketch side or is it not successfully pasting into Axure RP? If you can also provide a video of an attempt to install the plugin or of how it isn't working, please post that or send it over to us at email@example.com.
Just a quick note about the "AxureRP 2.sketchplugin" file rob002 mentioned: this is likely the result of Mac automatically adding additional numbers after file names when copies of the file have been previously downloaded before. The latest version of the Sketch plugin can still be downloaded via the download link provided in the original post.
Thanks for your patience–we'll be standing by!
