speedtouch 330 install problem again
 

Installing speedtouch 330 on MDK 9.2 Have read thru previous posts on this issue, tried speedtouchconf, but to no avail, I get modem_run error 250. Both lights on s330 are on all the time, no flashing.
Have tried the various methods I've come across, including, at last attempt, reinstalling MDK and starting again with speedtouchconf. help!
