I imagine the free webhost was probably running an older version of PHP that was causing the errors.  I generally don't worry about writing code to support anything before 5.3 anymore because of security issues with older versions.  I know I've helped a couple of people set up accounts on Godaddy that work fine.  Not my favorite host in the world, but I can confirm they do work.

As for updating my version of the bot, I may do it at some point in the future, but I don't have any time right now unfortunately.  If you're interested in lending BTC/LTC, I'd just use deponzits version at this point.  If I make any future updates to my version, I'll probably try to merge his updates back into mine, or somehow work to make them compatible.
