I would just like to add that. My friend and I have been having trouble with Res:1.91. We used to be able to play with 1.91 with no troubles at all, and now all of the sudden it doesn't work. I have the same setup as I had in the past. Last night we decided to give the Classic Flashpoint a try. Everything worked flawlessly.
I am not sure if BIS had updated the 1.91 patch for some reason without notice, because I did a fresh Windows install and re-downloaded the 1.91 patch for GOTY Edition. This seems to be when all the connection problems occured. I will have to do a search through my back-up disk to see if I could find and older dl version of 1.91. If this happens to work then there is something with the current DL of 1.91 on the sites.
My Specs:
Windows XP Pro with all updates
AthlonXP 2000+
ATI 9500 Pro 128mb (3.7 Cat. drivers)
Asus A7N8X Deluxe PCB v2.0 (1.04 BIOS)
512mb Geil Dragon (Dual-Channel)
SB Audigy 2 (latest drivers)
Network
Cable
NVIDIA nForce MCP network card (latest drivers)
Netgear FA311 (latest drivers)
Netgear Router(RP614) using the latest firmware, running also through a D-Link Switch
I hope this will get resovled soon, as I like to play OFP all the time. I guess for now we will have to use Classic OFP. All in all this game still rocks...
