Hi, I have to ask you refund my 论坛币. I can't open the file. Thank you.
By reference to the download history, you've only downloaded part one of the two files. To successfully
extract the compressed files, you have to downloaded the remainder and put them into the same folder. Then, I am sure a pdf file, which can be opened either by Foxit or by Adobe, will spring out.
If it was because you thought the book is sold at 100 in total, a price you can afford, but not at 100 for each part(i.e., 200 in total) that you determined to buy it, I would reimburse what you've paid in full. If so, please upload a file whose selling price is 100 and inform me, I will purchase it.
Please kindly note that the attached book has temporarily been downloaded for six times, nothing but your doubt on its accessibility and readability was remarked. I think this phenomenon can be explained as the asymmetric responses of the market to goods. That is, 对于好书,只下不顶。
