I would recommend to ask in their support forum:

It probably is related to your Windows, I assume you run Vista or W7!? If it is not that, then they may refer you to Codemeter directly, if it is an issue with the dongle software. Anyhow, the support forum is very helpful and has competent people from the company answering, so - ask them. It's the fastest way to get the issue sorted out.
You must not repeat the SBP program installation, it probably has nothing to do with it. The dongle software runs indepedent from that.
You could also enter the script name into Google and try what happens if you manually download and install it - in case your Windows indeed is missing a vital file, maybe it got deleted during an earlier software deinstallation.
