Imported donjon tsv file consistently crashes

It seems I can only perform one action on this map, the very next one crashes it. I'm trying to do the things on the youtube tutorial: apply texture to solid, floor and walls. Attached is the tsv file. I'm on Windows 10 with a decently beefy computer. I've tried compatibility settings for both Windows 8 and Windows XP (Service Pack 3). I have not licensed the product, yet. Just wanted to see if it worked with donjon maps (which I use with some frequency). Everytime I perform a second operation on the .tsv map, the product stops responding and must be shut down via the task manager. Any thoughts on what's wrong?

Just saw this message. I've downloaded your TSV file and will get back to you once I've tested it out.

Syneran, I was able to import and render your TSV file just fine. I initially suspected that it might be larger than the 40x40 map square limit in the free version of MapForge, but that wasn't it at all. Your map is only 30x33 grid squares. FYI, I used MapForge v1.1.7. Which version did you use?
