I have not used the IB TWS version. You can only run one version at a time, so I am running the version for IQFeed now. One thing I found out when I switched from Esignal to IQFeed was that my old continuous contract symbols from Esignal caused the server to crash. I would get that "Loading..." message in the Hyperserver and then it would start spitting out error messages and then go down. Once I removed the old symbols from the GS everything worked great. So make sure your symbols in the GS are the same as in TWS, as that could be the problem.
My only complaints so far are that I can't seem to disconnect a symbol with the Hyperserver feed like I could with the built-in Esignal feed, so I had to actually remove the old tickers from the GS instead of just disconnecting them. And you can't run the Online Downloader at the same time the Hyperserver is running for IQFeed (this is different from other data feeds, as I was able to run the downloader at the same time with Esignal). I was told by their very responsive customer support that the new version of DTN's API should fix that problem, but I don't know when that will be available.
Overall I have been very happy with it combined with IQFeed. It works just as well as when I used Esignal so that allowed me to cut my data costs in half.
