CR Not showing DATA

Hai there...

I am working with VB6, CR8.5 and Access2000.

I designed on report in CR. I called it using Crystal report icon (not from viewer).

It is not showing data. Only header info and footer lines it is showing.

when i refresh CR for 3-5 times it is showing data.

In the mean while it is not giving any error message or any other problem.

In the same manner i created 5 more reports they are working fine... but unfortunately it is causing me... headache.

Please save me.... from this problem

Thanks in advance.
