confused

Hey everyone, Just wondering if anyone has dealt with a similar issue before and how they went about to solve it? I've recently been invited to apply for a 190 visa but when I tried to apply online, I got the following error when I went to confirm my personal details. An error has occurred One of the following issues is preventing this application from continuing: The applicant has a previous visa cancellation or refusal. The applicant does not hold an appropriate visa. The applicant has a condition on the current visa. The applicant's location cannot be confirmed. The applicant is an Australian citizen or a permanent resident. The applicant will not be able to continue. The applicant should review the eligibility information on the department's website. I currently have a Briding Visa A from my application for a graduate visa so that shouldn't be an issue? I did have a refusal for a PR visa around 2000 when I tried to apply and it got refused and I had to go through ministerial intervention to get my student visa to continue studying in Aus but I didn't think this would be an issue as long as I detailed the thing on Forms 80 and 1221. Anyway, since they might not even be the reason for this error, anyone have any tips? Feeling a bit apprehensive since I can only call DIBP on Monday :(. Cheers! Andy.
