have used 5.0 successfully in the past and got 5.2 a few days ago. 5.2 did work for one game (copied to e:games). i copied some stuff on the f drive over to my pc and i think i used the dvd2xbox browser to delete some of the directories afterward (some deleted through ftp also). think it was after that that 5.2 stopped working. i can still use the browser (the B button), but it would freeze when i'd press A. i did try deleting the dvd2xbox directory and "reinstalling" a number of times. i think it did work one time after that (get to the destination list after press A), but i didn't go through with the copy because the game was too big for my f drive. after that it stopped working again.
so, i'm not sure why it happened. along the way, i thought that i was losing space on my F drive. thought that files/directories that i had deleted weren't freeing up space or something, but i might have just forgotten that it's only 2gig and not 4 like E. i did reformat F a few times but that did not fix 5.2 freezing on the A button.
anyway, just got the tc1 and tc2 zip and have successfully copied a game with tc1. haven't tried tc2. i have 1.0 xbox, stock 10gig HD, stock Thomson DVD, chameleon modchip, evox 1.8.3921 dash, evox M7 bios.
