appa00c,
Sorry that you are seeing this issue.
> Can you please clarify whether you have restarted MyEclipse after updating subscription details ?
> Can you clarify whether a report (reportname.rptdesign) file is opened in MyEclipse ? Data Explorer allows you to create a Data source only when you open a report in MyEclipse.
If you are still seeing the issue, please attach your MyEclipse installation details from MyEclipse > Installation summary > Installation details ? Also share your MyEclipse subscription details by sending a mail to support@genuitec.com. Please add ATTN: Pradeep in the subject and refer to this thread.
