Since the new update I am having issues with previously used SVG files being loaded as solid black or a mish-mosh of line segments. I have redone the SVGs but the results are the same. Any suggestions?

Proper save options for illustrator CS and newer, and new inkscape versions, are discussed here:

for help with a specific SVG, attach the SVG to your post.
