Here's a quick fix that might work:
Run msconfig, then get to System.ini
In the [386Enh]section look for the MinSPS= entry.
If the entry exists, try setting it to the exhisting number*2 (Unless in the error message there was a line saying "there are currently nnn SPs allocated". If you saw this, then set the number to twice the nnn).
Apply, close, and restart.
If the entry does not exist, then add a new one MinSPS=8.
Apply, close, and restart.
If this doesn't help, try increasing the number by two a couple of times. If that doesn't help, then I am wrong :).
