SUGGESTED

Please help.  My desktop died - motherboard fried. 

All my S/A data is on an external drive. 

I have purchased a new computer. 

I have re-installed S/A onto my new computer.  I need to restore my company data onto S/A 2008. 

I need help to do this. 

I do not wish to purchase S/A 2014 as I am closing this business in February 2014.
