[I cannot install 1.20 still]

I have forgotten to post that I have formated mi HD several times, I it hasn´t worked anyway. Well, I think I have tried all what is on http://www.theavonlady.org/theofpfaq/trouble/checksum.htm , even BIOS, chipset, HD Controller, nVIDIA driver, I have VIA 4-in-1 last driver, I have tried to install a HD driver which VIA recomend to install apart of the VIA 4-in-1, but this doesn´t work.

[I cannot install 1.20 still]

Well, I have tried to install 1.20 many times and with different ways. Disabling DMA for HDs en CD-ROM, disabling 4x on my VIA Chipset, changing my RAM Clock speed from 133 mhz to 100 mhz, replacing my CD-ROM, my CD-ReWriter, etc.

I played OFP 1.30 a long time ago   but now, I can´t, I don´t know why. Just a moment ago, I have just installed OFP and upgraded to 1.20 in my old K6 2 500 and it worked perfectly!. I always have the error in DTA/Sound.pbo.

My PC is:

-AMD K7 Duron 700

-Motherboard ASUS A7V133 VIA KT-133A with BIOS 1006/FXD.

-256 MB RAM 133 MHZ

-nVIDIA AOpen GeForce 2 Ti 64 MB DDR

-CD-ROM LG 52x.

-CDRW AOpen CRW2040 20x10x40x.

-Two HDs Seagate 20 GB 7200 RPM UDMA100

-Sound Blaster 128 PCI.

-Windows XP Pro.

Please help ´cause I wanna play OFP the sooner the better

 Thank u very much everybody.
