If it was really only a few hours ahead, then you should be able to disconnect the dongle for a day, and then get it to work later.
I suspect the issues here are maybe even more basic.
The "can't open IBU port ..." means that the computer can't even communicate to the dongle. Did it every work? Check that something hasn't happened to the driver. Sometimes I notice that Windows laptops are sensitive to which port you were plugged into when you installed the driver.
Once you guarantee that the communication between the machine and the dongle are working (I use spm_key_ib -t to check), then you can turn on the spm service. By the way, key installation and checking cannot be done with the spm service on, so remember to turn it off.
There is both a UI way to do these things and a command line way. On Windows, I always use the UI in the Services control panel window to turn on and off the service.
