Budget imported with wrong dates

[Liam98]

Hi there

Apologies if this is the wrong area of the forum - I was tossing up between here and Sales & Purchases. 

I'm asking this question on behalf of a friend who has imported a budget into AccountRight (latest version). After importing they realised they had incorrect dates on the budget, but unfortunately had not backed up the file before importing this. Is there a quick way to reimport the budget with the correct information and dates, despite not backing the file up?

Cheers

Liam
