cannot add new data line manually after new version upgrade  [SOLVED]

Hi.

I manually add data daily to keep my database.
after upgrade to new version of MC yesterday,
I cannot save data.
I do 'edit data -> load -> add -> ok' but data's not saved.
how can I solve this?

p.s
i happened to know that, not just adding is not possible,
also editing existing data is not possible.
i tried to modify one data and save it, and this is not possible also, data just stays still.
so.. i guess the problem in common is 'save' part

funny thing is that.. i tried to add 2 lines, and it worked.
tried to add one line, again, it didn't work.

p.s again
if you can't help me out this problem, plz send me prior version of MC
or teach me where i can download it. my email address: duffrank@naver.com
this problem makes me work an extra hour,
because i am doing all my database job through excel,
which is driving me crazy..
