Original Shadows of Amn (CD installation) and Near Infinity

Hi.

First post here by me.

I've recently installed almost every version of Baldur's Gate, then copied the game files to backup directories, and now can access original and enhanced, patched and unpatched, expansion and non-expansion versions of each game.

Just now I stumbled upon an issue, though. Reading with Near Infinity the files of the unpatched and patched Shadows of Amn (without ToB) seems to be working in general, but certain items give an "Error reading XXXXXXXX.itm null" (where "X" are placeholders). This starts with the first item in the list, ACIDBL, and goes up to AEGIS2. AIFAST then is okay, but further down the list, these errors will happen again.

I installed from the CDs, copied, patched, copied, uninstalled, and then did a clean new installation together with the Throne of Bhaal CD. From these files, all items work.

Any idea where this comes from and how to solve it?
