Runtime Error after updating Yahoo Messenger: Object Expected Error

I updated my yahoo messenger last night and turned off my computer afterwards.
When I woke up this morning I clicked on yahoo messenger clicked on the mail icon to see my unread emails but when the browser opened I suddenly got a runtime error message.
Can anyone help me with this?
Even if the browser and messenger are running fine the runtime pop outs annoy me.
