Version 1020o stopped working

I had version 1020b working fine, then it suddenly stopped receiving data. Tried reboots, etc, then updated to 1020o and still nothing. Wx station is ultimeter 2000, data logging mode. I tried complete station reset and different modes. Top data light is green, bottom is red. I can get max wind info but nothing else. When I set the wx station type, the program will not remember it on the next reboot. Data to another program on different computer is okay, and data to wall led wx display is okay. Computer is intel PIV 2.4MHZ, 512 meg ram, windows xp.

check under view, program error log
there might be an error there
let me know

the error is I/O error 112 at timeā€¦Thanks

Windy: I think I solved the problem. I found an old post under hints and tips about deleting some .inf files(latest,latestindoor,grafdata,2,3,and24hourrain) and restarting. One of those must have been corrupted. That seems to do the trick. BTW, I am using the program to upload to CWOP via APRS. I am sending the Data and log files to a CF card in a USB port, thereby eliminating the constant writing to the hard drive. I just specified a new location for those files under setup that corresponds to the location of the card.
