If you're not seeing any user-defined PRE-FORM / BLOCK / FIELD diagnostic messages, then the form is not being instantiated.
You mentioned in your original post, "/All my other forms are coming up fine. The form just sticks on the gray screen and does not go anywhere/."..

Most Forms have a CONTROL block - for initialization and *user-role* / Authentication checks etc. The CONTROL block is not typically a navigational block. If user-roles are being checked, and don't exist in the test VM, this maybe another reason the form is not instantiating - AND you're not seeing any errors or messaging.
