Help to change Incredimail email address

[Blackburn]

Is anyone out there who can help me? I am registered with Incredimail for emails & I need to change my email address with them & although I have tried every which way to find out how to do this I cannot find a link within incredimail.
I would appreciate any help I can get as it
is driving me crazy. If I am unsuccesful I will have to remove Incredimail & go elsewhere. Thanks to anyone who can give me an answer.
