Our system is designed to alert you if you are submitting an invalid file.

However, in very rare cases, the file you send us may need to be revised.

The most common scenarios are:

• When your file does not contain a video, you uploaded a PPTX file instead of a PDF. Please save your file as a PDF first, and then try uploading that instead.
• Your poster contains more than one video.
• Your file was converted improperly into a PDF.
• Your poster does not meet the guidelines requirements.

If you believe that there's something else wrong with your upload, please do not hesitate to reach out to our support team using the chat widget on the bottom right of the screen.
