I took a look at the set-up of the web hosting accounts and both are proper for running Tasks Pro™ and/or Tasks. ThinkHost has also said they will offer some assistance in creating the needed CRON jobs, etc. if you need the help.
To accept this offer, log into the Download page and follow the links in the right hand column.
Full disclosure: if you choose to stay on with either company as your hosting provider, I will receive a small commission from them. This site, kingdesign.net and taskspro.com are currently hosted by Austin Web Development.
