We've recently upgraded a client from B9 to B10 and we now have an issue where an #ASCII #datareader that works in B9 no longer works in B10 because it cannot find the file which is in a different network location to BOARD.
The file is saved to the 'finance' network drive, and in the B9 (production) datareader (below) you can see all the files, and it can read the csv file required.
However in B10 (development) it does not, so the datareader does not work. I have RDP'ed to the B10 server and can view this location and the files in win explorer so there are no network access issues, it seems to be purely BOARD10 that cannot see the files.

We can implement a work around if required, but the preference is to keep the client's current process unchanged where possible.
This is the only file that is read from another network location, the rest are all extracts and reloads from the board/dataset folder.
Has anyone had this issue, and/or know how to resolve it?
