Two urgent problems, help please!
I've been using Illustrator to make commissioned logos for a client and the first one was fine, but now problems are arising. The first logo features three silhouettes of dancers. When the client asked if she could have separate files of each silhouette on transparent backgrounds, I did so by making the rest of the logo invisible and sent her the files, but despite them working perfectly on my computer she says that when she opens them, the entire logo shows up instead of just the visible layer. I can't figure out why it would do this, or whether she's just opening the wrong file because the problem doesn't show up on my macbook at all.
A second logo I'm making for her is causing equal problems if not more concerning. It requires tracing over a reference image (the original logo of hers which I'm fixing) but despite trying everything that comes to mind, it won't allow me to use the paintbrush. I've restarted the program, checked that all layers are unlocked, the right layer is selected, a brush and colour are selected, I can't figure out what's wrong with it. Hopefully someone will know because right now this work should have ideally been completed already and I can't keep the client waiting too long.
