Hi Stephen,
<div><br>
</div>
<div>I've had something like that happen to me before. In my case, the culprit was either the wrong line endings (for example, Unix vs Windows line endings) in the material file, or some other invisible characters that threw off Gate when reading the file.</div>
<div><br>
</div>
<div>I suggest you create a new blank text file and copy the material database to that new text file (all within vGate). Then use this new material file.</div>
<div><br>
</div>
<div>And if this does not work, then I do not know what's going on.</div>
<div><br>
</div>
<div>Good luck!<br>
