Reserved Error on access import into Reporting Services

Error 14 An error occurred while the report CFPM001 - Portfolio Collateral Summary was being imported: Reserved Error 0 0

when I try to import access db into my visual studio reporting project. I have searched ev开发者_运维知识库erywhere and nothing has been able to point me in the right direction. Is their anyway to debug this or find out what is happening?

Sounds like a problem I'd not want to figure out. I'd delete the report from access and recreate it by hand, why waste the time if all the others work?
