Table Not Found

Table "TRAVELREQUEST" not found

I just downloaded Bonita Studio Community v7.8.3 and am following the Getting Started tutorial. I am stuck at the step "Run process with temporary forms". When I click run, the web browser launches the form and I can fill out the details, but when I click submit nothing happens. Additionally, the validation constrains are not displaying on screen. I have checked the engine log and notice the following (full log follows). Has anyone had a similar issue?
