MS error message - need help - please

hi all - first post - unfamiliar territory - looking for a helping hand
been trying to open/use an old app - dev'd about 5 or 6 yrs ago - uses an export/import function to an Access db. I'm on Vista Home Prem using Office 2007 [app was dev'd using Access 2000]....keep getting "Data source name not found and no default driver specified".

I am not a db guy nor a prgrmr but I have just enough knowledge to really f'up my machine and i'm well on my way....i've tried some benign tinkering inside Vista's admin tools but nothing has changed.

Can anyone help me decipher the following and explain it to me as if i'm a fifth grader?:
