Hello Alexandros Philippou,

Please check this article and let me know if the workarounds provided here worked: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0028688. I would also advise checking this one: https://community.sdl.com/product-groups/translationproductivity/f/studio/36340/the-current-configuration-on-stack-is-different-than-the-one-supplied-error-message. 

Best,

Hi Alina, I initially tried to figure out a solution with those articles on the side but since weren't mentioning PDFs it was kind of a problem. I also tried to convert the PDF into Word but it gave me the same problem, and at that point I figured out that the the original file was likely damaged. However it was enough just copying the Word's content into a new Word document and it was accepted within the project. Thank you very much anyway!

I'm very glad to hear this, Alexandros! You're very welcome.
