Exporting reports to Excel error

Hi,

 

Today I'm getting an error when trying to export a report to Excel.

 

It tells me that the file has been blocked by the Excel Trust Center setting.

 

I've checked the setting and all boxes that need to be ticked are ticked.

 

Last week I could export and work in the Excel files without any problems, this week I can export and I can't work in files I created last week.

 

Does anyone have the same problem, is it MYOB or Excel, have you been able to fix it?

 

Also, why doesn't MYOB export in the current version of Excel.

 

Thanks

Shaun
