If someone asks a file in an editable program, it could mean that they do not trust your work to be properly prepared. If you really used paths in Photoshop, (Which means you used almost entirely the pen tool) you can export the paths to illustrator, and simply open these paths in Corel. Depending on the assets included, and the type of design, there is a biiiiiig chance you need to make it correctly. The second, you used PhotoIShouldNotUSeItForEverythingShop.

The first one, you did not ask the requirements beforehand.

You have 3 problems, and all caused by yourself.
