Hi guys, I always have these out of frequency range problem when installing new Cat drivers. It happened in Cat 3.9, and now happened again in Cat 4.1. I tried Omega drivers and still same thing happened. After the installation, and I restarted my comp, the boot up image came up, and then it was just black and said frequency out of range. I tried to boot in safe mode to install, but it's just like it embedded in the drivers. It didn't happen in Cat 3.10 though cause right now Im using Cat 3.10. I really hope that they won't make this problem happened again in the future. Unless anyone know how to fix this right now? thx.
