i'm trying to run a 2nd party timexp module to my DNN site (v3.2.2, .net v1.1.4322.2032) that is running from a shared hosting provider's environment.  essentially, its the time tracking system that has been converted to use the login and users from DNN.  it installs clean, but whenever I try to do any admin function (e.g., add project, etc.) I get an error--- I know this may be outside the bounds of this forum, but I thought someone may be able to point me in the right direction.  thanks.
