The client just stops responding right after it reaches the login screen. Pleione engine hasn't even started loading yet.
I'm using a working customised UOTiara from like 10 versions ago, tested working without Abyss. When I add Abyss in, the client stops responding, even with NO patches enabled. It's been like this since Abyss moved over to ijl15.dll back in R147. It used to use dsound.dll, and I've been using the R146 Abyss (dsound.dll) since ijl15.dll isn't working.
Do you have racedb.xml in your data folder?
I was dicking around with that this week, I can't make ANY edits to it without the client doing exactly what you describe.
Did you use the data packer by any chance?
Also, everyone who has an issue, run the batch file I uploaded on the previous page (in your mabi directory), and post the results as per that post.
This is to help you all as much as us, the less time we have to spend back and fore-ing for that information, the quicker you'll be playing mabi.
Edit: also, anyone getting an error that looks like this:

Should remove their data folder.
The above was from a data/db/racedb.xml edit. Any editing of that file causes the above.
