I got Photoshop Elements 15 as a Birthday present from my boyfriend in August, and I want to make use of it but for some reason it won't open anymore, despite working fine when it was first installed. This laptop came with windows 10, has not been upgraded to it. No error message is shown when trying to open it- it just opens a new tab at the bottom of the screen but goes no further than that. I'm scared to uninstall it then reinstall it in case it doesn't let me re-use the code. Advice, please?
