What steps will reproduce the problem?
1. download xiangya-medical from
http://nchc.dl.sourceforge.net/sourceforge/stardict/stardict-xiangya-medical-2.4.2.tar.bz2
2. upzip to 2 files xiangya-medical.dict.dz and  xiangya-medical.idx, upzip
xiangya-medical.dict.dz to xiangya-medical.dict using 7zip
3. zip the 2 files to xiangya-medical.zip
4. upload xiangya-medical.zip to an intranet httpserver
5. open wedict pro, settings, download from url, input url, "go". after
download successfully, ipod hang for about 20-30 seconds, then restart.
reenter wedict pro, the xiangya-medical dict is there, but whatever word i
input, xiangya-medical dict gives nothing. Then i disable 2 default dicts,
only enable xiangya-medical, querying any word will give me "Not Found"
6. i surf the internet for any solutions, anybody said wedict pro need
another index file named as xiangya-medical.idxc, so i downloaded it and
zipped it into xiangya-medical.zip, then retry step 4-5, but it still did
not work!

What is the expected output? What do you see instead?
when i query a word such as "ureterocele" or "cancer", the xiangya-medical
dict should give me result.

What version of the product are you using? On what operating system?
wedict pro 1.3
ipod touch 2, 2.2
