PRS-T1 problem importing book bought from google

hi

i have today bought my first book from google books. i found the link to download the epub drm to computer and did that. i then tried opening link acsm file(which normally opens book in reader software and thereby adds the epub to my library). this did not happen correctly and i am now stuck.

problem is that when i try and reopen link it tells me that the book is already in my library(i cant see it). i have deleted all the books from my library and even reinstalled the sony reader software. it still tells me that the file is in my library.

what am i missing.

this process normally works fine with books from kobo so i dont know if is a google issue with file or my computer.

hope someone can help

thanks
thomas
