I CANT EVEN DELETE A SINGLE TEXT FROM ACROBAT 9.2 arghhhhhhhhhhh!!!!!

I have never encountered a more frustrating program in my life than Adobe Acrobat Pro Extended 9.2 , Ive spent the last 2 days trying to erase one measely word from a scanned document saved as a pdf file.

It lets me cross out the word with a red line using the "Touch Up Text Tool" however when I hit delete to erase the word completely it wont do it it just ends up deleting the red line instead. When I delete something I want it GONE not a ridicilious red line over it to add a mark up or comments to!!!

Because its a scanned document its failing to recognise the text as a standard font so I tried treating the word as an "image by selecting "edit image" and that failed, so I try deleting the word by treating it as an object by selecting "Touch UP Object Tool" and it still wont erase it, then I try selecting "Edit fields" from the forms menu and then clicking on delete but instead it actually ends up deleting the whole page when it cant even delete one simple measely WORD!!!!!!!!!!!!!!!!!!!!!!!!!!!

It obviously recognises the text because I can scroll overit and highlight with the cursor or locate the word in the document search menu then why wont it let me delete the dam thing ?

ARGGGGGGGGHHHHHHH!! It has me so frustrated!!@!@

I went out and bought adobe acrobat in order to be able to delete a misplaced word ina pdf document and I feel like I wasted my money on a program thats takes up over 1 GIG space yet it cant even do a simple delete function.
