I tried to send this as a PM here but your box is full LOL.
Its easier to post piccies here

Opening screen - non plane textures already listed

Click start_ plane and multiskin textures added- there is the 1517 just as it should be


There is a "newlinks.txt" file available (actually a copy of "nplinks.txt" used for testing)
Select and click "Read"
It appears in the listbox, which could be cleared if you made an error

Click "Add loaded links"- there they are at the bottom of the two lists

Click "Save stringfiles". Thats it!

Reading "TexMap1.str" from the top....

....to the bottom
