Adobe PDF to Word Conversion

I recently purchased a subscription to Adobe Reader, so I could convert my business files from PDF to Word, and whenever I end up downloading the word file, it changes some of the words.

For example.

I had a file I have to send to the state, and I couldn't figure out how to add signatures through word, so I printed it out, signed it, and date. When it converted to Word, it had changed a lot of the words, and the Date had a whole bunch of random letters and images in its place. Also, I had check boxes that converted into letters instead of remaining check boxes.

The entire reason I bought this was for the conversion to work, so am I going to have to just give up, and cancel the subscription or is there a fix to this?
