How to delete a process instance for a invalid XML?

I'm currently facing the following issue:
1) My old deployment uses a (now) invalid method signature
2) Whenever I try to delete de old active instances, I get the following stack trace:

org.activiti.engine.impl.javax.el.ELException: Parameters for function 'mylib:myfunc' do not match

Point is, how can I delete instances even if the deployment is not valid anymore?

Thanks,

Login in activiti-explorer with your admin user. Goto "process" tab. There is a tab named "My Instances". There is a list of all active process instances. Click on particular process instance which you want to delete. In right hand side, you find "Delete" button. From here you can delete your process instance.
