VB Unpacking

Trying to unpack VB application I exprienced that I have th dump allright. While in debugger it would show call vb dll however in dump the direct call to api is reduced to indirect calls and most of the reversing tools fails to acknowledge it as aVB application and so refuses to work. I tried import rebuilding usinfg ImpRec but without any success.
Can i have some suggestion how to unpack VB properly with proper api calls
