RE: dll problem on Remoting app

Hi Steven.
first at all thanks for your time :)
I'm it took so long but I was trying to find out what was wrong and it takes
a litle bit time to test everything.
My status is as follows:
We find out at when we register a PB.dll version 1.0 and uses this in our
app it fails.
When we register a PB.dll version 1.1 and uses this in our app it fails.
When we register a PB.dll version 1.0 and uses this in our app and then we
copy over the file the 1.1 Version It works.
When we register a PB.dll version 1.1 and uses this in our app and then we
copy over the file the 1.0 Version It fails.

Any clue??
I'm very lost here.
