TRose errors are ALWAYS due to an invalid packet coming from the server.
By invalid i mean one that the client is not equipped to handle.
This is almost always because your client side STBs do not match your server side STBs (or CSVs or SQL depending on your server version)
Like lmame said, this issue has been addressed hundreds of times. It is the most common error that is ever reported and it's ridiculously easy to fix if you just use SEARCH
