Canon Powershot "Communication Error" solved

For the past few days I've not been able to connect my Canon Powershot Elph 520 camera to my computer with its usb cable to extract my photos. When I tried, the computer would do nothing (no bing or anything) and the camera would momentarily blink "communication error". I discovered the problem to be TOO MANY IMAGES! The 32 Gb card I put into it was over half full, meaning it had thousands of images I'd taken since December on it. Once I deleted a few hundred of them, the camera works again. I was worried because they told me at Don't Photo that sending it out would have me without it for 4-6 weeks, which is most of the summer.
