Hi Josh - I see Lucke - provided you with the guidelines, however if you have a QDCB subscription you should be able to upload a file that is 150MB in size.
Here are some things to verify:
Can you provide a bit more information and perhaps a screen shot of the issue?
Just for reference, are you sure your are uploading the data in the Workspace area AND that you are a designated editor role? Sometimes people upload to the Personal area - which is limited to 25MB.
