After happily scanning a few images I now get this message when hitting the scan button:
---------------------------Corel PHOTO-PAINT X5---------------------------The application could not inquire about the palette of the image from the Twain driver. Image acquiring aborted.---------------------------OK ---------------------------
I have a feeling it may be something like the temp files needing to be deleted, but I'm not sure where. Any suggestions?
Go to temp files in your Windows user profile (Windows Key + R, then type in %temp%). In temp files, look for file names like Twain001.Mtx and TWAIN.LOG. If these file exist, delete them and you are fine.
