My BitComet 0.70 Problems

[Ghostalker]

I'm a newbie here so I'm not very sure if it is alright to post it here:

1. 0.70 crashes everytime i try to close it

2. 0.70 crashes after about 3-4 hours use OR after about 500-600mb download, whichever comes first (This is getting to my nerve since I have to check it once in a while to see if it is still working or not)

Note: I do not know if it is a bug or what, so I want to apologize now if this post is incorrect.

Thank You!

Addendum:

So it happens again, 0.70 stops responding after hitting 600mb...

after 600.12mb stops

after 600.58mb it stops again

after 595.00mb again!

That's just from yesterday till today a.m.
