I have no idea why this problem occurs but when I export a file (tested with jpg, pdf and png) in Affinity Designer on my macbook pro (High Sierra) and send it to my coworker who works with InDesign CS5 (Windows 7) she can't place my files.
When she tries to place a document it says "The file does not exist or is being used by a different program, or you don't have the proper access rights."
It never happens with other files. Only with the ones I exported with Affinity. The craziest thing is it even happens when she makes a desktop screenshot! But only if my file is seen. It doesn't make any sense to me.
She can place the files in Word so they are not actually broken or locked or something!
I would really appreciate any help. I'm going mad.
