C# InvalidActiveXStateException

Question

I'm currently trying to use an ActiveX on my application but i've got a InvalidActiveXStateException and i don't know why :( Here is my code : private AgentObjects.IAgentCtlCharacterEx Character; private AxAgentObjects.AxAgent axAgent1 = new AxAgentObjects.AxAgent(); .... private void lecteur_mp3_Load(object sender, System.EventArgs e) { axAgent1.Characters.Load("merlin", (object)Application.StartupPath + "\\chars\\" + "Merlin.acs"); Character = axAgent1.Characters.Character("merlin"); Character.Show(null); } Error in on this line but i don't know why : axAgent1.Characters.Load("merlin", (object)Application.StartupPath + "\\chars\\" + "Merlin.acs"); Any ideas ? Thanks
