RF ONLINE: Revised: Critical Error Fix Guide.

*** Disclaimer: This guide is not for the weak. This is not a spoon feeding session. You must figure out the rest.***

There are a couple of things that may be causing your RF client to go critical on you. A couple of them are listed below:

Damaged/Corrupted files or sectors on your HD

This may entail you to reinstall the RF Online Client. Most of the time it’s the rfonline.bin or rf.exe is damaged. Make sure that you always have a saved or back up copy of the two files.

Virus/Malware infection

Yes it sometimes happens, when your computer is infected that it just messes up your operating system.Run your Antivirus Scanner and update it. I suggest you try and download Malwarebytes from www.Malwarebytes.org. Download, install update and scan. Also, if your homepage is mywebsearch.com then its an indication that your host file is messed up and you have been malware infection. Same goes for if you see a lot of pop ups.

Damaged/Corrupted Visual C++ library

Download and install the Visual C++ Redistributable copy. You can get it on the link below: vcreditist_x86.exe icon.

Old Windows XP SP2
If your still too stuck in windows XP SP2, I suggest you update to SP3.

For Windows Vista and 7 you folks should be fine. Instead, make sure that User Access Control allow
RF Online to run.

Cheating Applications
EagleNT errors: You cheaters stop with the hacks; eventually you will mess up your Ahnlabs registry and give you crit errors. Also do not run WPE, Cheat Engine (and its many mods), MHS, ArtMoney, and the other cheating apps. 

If you plan or use hidetoolz or Process Hacker ( use for multi logins ), make sure you know what you are doing.

Ok, I will leave everything to you now.
