I was able to change the iscore logo on the top bar, but how do you add other items to that? Also is there a way to move pic around the front page once you add them? I can only move them left, center, right etc.

Thanks

The "logo" can span the entire width of the top area, so you can create one graphic that includes anything you want across the top.

For the "front page", if you want to just move a picture anywhere on the page, you can use the button that says "Insert new layer" (rectangle with dots around it), then add an image and drag the image inside the layer. The layer can be positioned anywhere you want it on the page.

I have mistakenly uploaded a .pdf graphic. Now, I am getting a message that says "FAILED: File is an invalid type". What should I do now???

You should be able to just remove the PDF and upload a corrected graphic. If you are having trouble doing that, if you can be a bit more specific about where you are having this trouble, we can certainly help out.
