[RTTY] Problems With Digipan & Rigblaster Plus On PSK31

[XTRACLASS at aol.com]

I recently switched from Writelog to Digipan 2.0 through an Iogear GUC232A  
USB to Serial Port Adapter to my Compaq Presario 730 laptop.  Digipan works  
great on receive but my  Digipan Program and my computer locks up every  time I 
hit the T/R switch to transmit.  At Randy's (WX5L) suggestions I  removed 
Digipan and downloaded it again in case the file was corrupted on  the first 
download but no luck.  I have downloaded WinPSKe and everything  works fine so I 
don't think there is any problem with Rigblaster.  I have  spent a dozen hours 
checking the setup instructions for Digipan and the computer  soundcard 
settings and can't find anything done wrong.  Has anyone ever  experienced a similar 
problem or have any suggestions for anything else I  can try?       Thanks & 
Happy New Year To  All  Paul  WT8S
