In TR's Port Telvannis, I had to buy an note called "Hospitality Papers" to have access to the town's services. When I equip the item to read it, the game crashes.

The version of TR I'm using is the latest (14.08), but the same happened with an earlier version (Map 1 Telvannis).

Google didn't return any info about this problem, apparently no one had the same CTD.

I have no other mods installed besides TR.

Weird. Which version of TR did you install? You should grab the newest alpha version as it's the most complete. Also, did you register the TR bsa in your .ini file?

Please post your mod list and the contents of your warnings.txt file (after inducing the hospitality papers crash).

Yes, the BSA files were correctly registered in the morrowind.ini. I played TR for quite a long time before going to Port Telvannis.

My game files order was simply:

GameFile0=Morrowind.esm
GameFile1=Tribunal.esm
GameFile2=Bloodmoon.esm

GameFile3=TR_Data.esm

GameFile4=TR_Mainland.esm

Unfortunately, I didn't think of keeping the warning.txt after the CTD.

The only explanation that comes in mind is that it has to do with the syntax %PCClass in the text of the Papers, since I used a custom class, but then I'm hardly the only one who play a Custom class...

Also, I applied the MCP before playing TR.

Did you use the old http://mw.modhistory.com/download-95-5212 tool to register TR BSA?

If so then remove it since it's known not to register TR BSA properly. But I know and have confirm it myself that KINGPIX's http://www.theassimilationlab.com/forums/files/file/1059-kingpixs-useful-tools/ will work for TR BSA.

No, I always write them manually in the morrowind.ini
