did you ever figure this out? I'm having the same issue.
I have this software installed on my laptop and I am using IBM access connections to manage my connection. The wireless card works fine, and so does the manager. Problem is that when I boot, I get an error message that states the following.
Error loading plug-ins. Application will exit.
I click Ok, but the wireless works fine. If you leave the error up, the wireless works fine, and the application never exits.
I have uninstalled and reinstalled several times to no avail. You guys are my last hope.
