Problem Event Name: BEX, error message

I'm working on a tool which is used mainly for replacing the data source location of Crystal XI report batch, this tool is working normally, but when trying to replace data source location of some reports and mainly when looping on report tables to replace the data source of each table, a Bex error is raised

by the way, DEP feature is disabled using command ==>  bcdedit.exe /set {current} nx AlwaysOff


i need to know what is BEX error ?

why this error is raised when working with some reports not all of them?

how can i disable or work around this problem?

Thanks a lot.
