Dear Carlo,
According to your update, I thinke your upload data is very large, and I
suggest you to disable some of these upload data manually.
For your convenience, we can refer to these steps.
1: Use Grooveclean tool to clean the groove communication sessions:
1. Browse to C:\Program Files\Groove Networks\Groove\Bin and choose
GrooveClean.exe
2. In the Run box, the command line, should type:
C:\Program Files\Groove Networks\Groove\Bin\GrooveClean.exe
3. Click OK.
After these steps, please let us restart the computer normally and then test
the results.
For more information about using Grooveclean, refer to the following technote:
How to use GrooveClean.exe to clear communications queues or remove all
Groove data

After these steps, please let us restart the Groove and then in its menu,
please click Options->communication manager and then clear the box of the
activity which we want to disable the upload.
Best regards,
Gell
