I am a MASSIVE fan of your mods, but i am having the same problem with the path not appearing. all the sounds are the same, but the particles are just not there... I am using the default texture pack as well, i don't know how to fix it. please help.
I had the same problem as NorthStar, no sounds or path and the same messages from the error test. Tried using the 'j' hotkey though and that worked, still no sounds but the path shows and works just fine. I guess this has to do with the fact that, from what I understand, Minecraft 1.3 SSP now uses a server? Hopefully this is helpful for other people having the same problem.
I'm playing single player and I'm also having trouble getting it to work properly. Neither the right clock nor the J work reliably. I've had it work maybe 1/10 times, and it never makes any sounds. Too bad, I was SO excited for this. I'll keep my eye out for an update. Thanks for the great idea.
I crashed to desktop after hold-right clicking 3 times in 3 different locations to try it out and crashed to desktop while drawing back for the third. I found this in ForgeModLoader-client-0.log as there was no crash report anywhere.
Edit: I had a similar crash while doing something completely different, so this mod is probably not at fault.
