I'm no GM, but I can explain a few of your problems.
Linked item names are cut off/have gibberish added to them: This is due to the person linking the item using a different client than yours. Your client can't parse their links correctly, and winds up cutting them off. Clicking the link works fine, so it's mostly a cosmetic issue - you learn to deal with it after a while.
Zone Crashes: The SoD/Underfoot client from Steam has a lot of files missing. Try the guide Lillu links to in
this post to fix your client - you'll need a Live client & and a Titanium client to get all the required files that the Steam SoD/Underfoot client is missing.
Amazon.com Underfoot Client: Doesn't work. It's missing a ton of required files and has some bogus corruptied ones, too. If you're using this, scrap it - it ain't gonna work.
Hope this helps.
