From your explanation, it seems that you have 2 versions of the tool installed in your Galaxy instance, the original version and the new version that is broken. If this is the case, just uninstall the newer broken version, and continue to make only the previous working version available to your users.

Just today, we had a case where we wanted to rollback to a previous version of a tool that we'd installed from a toolshed. (No big reason except that our latest "fix" actually broke the tool.) Is there a way to do this? I could have sworn there was but couldn't find it in the admin interface.
