I have an issue with my Developer License. When I try to create, for example, a new Opportunity the System give me the below message back:
"Data Storage Limits Exceeded Your company currently has exceeded its data storage limits including an extra overflow buffer. Per our terms and conditions, we cannot permit additional data creation within our system until your company first reduces its current data storage. Please contact your company's salesforce.com administrator to resolve this. We apologize for any inconvenience this may cause.

I have tried to delete something like images (Mb), and still I cannot create an Opportunity. The same message appears if I create an Account, a Lead, etc etc.
Do you know a possible solution for that?
