VB3 decompiling

I found the Deprotector for VB AntiDecompiler tricks, but my two version of DoDi's decompiler can't decompile itself with diagnostics "Error in Discompiler logic!"
and the resulting source is not compilable. I don't know, if there is exists newer version of this programm (my most newer version is 4 Jan. 1996). But in any case i can reconstruct the decompilation algorithm and VB opcode from given source.
But, now i see, that this way is very long. Now i try go in alternative way.
I will intercept the USB traffic to the hardware via USBmonitor. and i hope, that this information will be enough for reconstructing of hardware interface

DoDi's decompiler can decompile itself using the deprotector. The only problem is that the source code is not complete but I think a person with a good VB knowledge (not me I'm afraid) could rewrite the missing pieces and possibly recompile it using VB6. I don't have the decompiled version left anymore due to a hard drive crash but I found similar from Planet Source code.
