ToME: the Tales of Maj'Eyal

I dunno, if this is a noob question, but how am I supposed to use this, what do I write for 'Folder Name'?

Oh god, FINALLY, thanks heaps =D it worked after flushing logs.

Soo, I used to play this, like 5-6 months ago, and I come back, and install the new version. However, after patching, I click the play button, and it opens a window named 'T-Engine 4', which is just a white screen. Any fixes?
