Avaya BCMR Error 8001, when user runs History Report, report won't run

[avaya033]

I am having strange problema, I have BCMR to run my Real-Time Reports for several ACD-Groups. I can start BCMS Server and system connects to PBX, I can perform Downloads. I can see Data running after running Updates or running Downloads, once this has completed I start my Client BCMR connection, once connected, I can run any Real-Time Report and the agents connect, But when I try to run a Historical Report Daily, Weekly or Monthly I an getting the following error: 8001 - Can not open File: < file full path name > Correction Indicates : Use Microsoft Explorer to check that the File Exist in the Location Path

Don't understand where and how to check or correct this error, 1st time this messages appears,. Previous Month I have been Running Historical Reports with No Problem. Need steps to correct error, using old BCMR Versión.

Thanks
