Can LibreOffice open adobe documents?

my computer will not open adobe anymore. i needed something similar to adobe. when i open the pdf file, it is just grey and blank.

I assume you mean PDF files - if this is the case, LibreOffice is not a good tool for reading PDF files.

Use your favourite search engine to search for PDF reader for whatever operating system you use.

yes that is what is what i meant. great. thank you so much.
