im all new to this so apologize for any stupid questions here but i have a T7 rebel and LR 3.3 (just purchased 4 days ago) and when i go to upload pics from a new sd card (sandisk extreme pro 128GB) the previews in add photos show up blank in .cr2 and .jpeg but i can not upload either format. but if i try and upload pics from a 12 year old 4GB kodak card it works fine. granted those previews show up .jpeg only but why can i not use this new card? thank you in advance
