Our systems are designed to alert you if you are submitting a file that is invalid.
In some cases, the file you send us may need to be revised.
The most common scenarios are:
• 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 a video*
• Your file was converted improperly into a PDF
• Your poster does not meet the guidelines requirements
If you believe that there's something 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.
