Hello Kimberly
I'm not sure if this is the correct answer to your question.
After you re-install Win98, you must load a driver for your modem. To do this, right click on My Computer, choose Properties. The choose the Device Manager tab. If you see any yellow question marks, right click on the question mark and choose Properties. Now choose the Driver tab. Click on 'update driver'.
Now you must browse to where the driver is for the modem. Is it on the disk that came with the new modem? Probably.
Now try Procomm. You must be absolutely sure your modem is working correctly to use Procomm.
I do not understand what you mean when you initialized the hard drive due to its failure to locate the modem.
Hope this helps steer you in the right direction.
Paul
