hi, when I try to open a uti or utc in kotor tool it comes up with this error. and i think the only part that matters is the "OutOfRangeException: Non-negative number required.
 Parameter name: byteCount" please help me fix this.
 
 
 See the end of this message for details on invoking 
 just-in-time (JIT) debugging instead of this dialog box.

 ************** JIT Debugging **************
 To enable just in time (JIT) debugging, the config file for this
 application or machine (machine.config) must have the
 jitDebugging value set in the system.windows.forms section.
 The application must also be compiled with debugging
 enabled.
 
 For example:
 
 <configuration>
 <system.windows.forms jitDebugging="true" />
 </configuration>
 
 When JIT debugging is enabled, any unhandled exception
 will be sent to the JIT debugger registered on the machine
 rather than being handled by this dialog.
  
 
  
  
    wow 66 views so far and it's been almost a month. theres not even one tiny piece of advice, or an opinion of what could be wrong. mabye I used invisible font or changed the language. come on at least someone tell me to figure it out myself or somthing.
  
 
  
  
    Do you have latest Kotor Tool installed? The latest version is v1.0.2210.16738 (2006-1-19 12:38). Try reinstall the tool. What is your version of .NET Framework? Does the error affect all uti and utc files or are there any exceptions?
  
 
  
  
    I'm sorry I forgot to mention that I use the xbox version and so I am required to use the last working version for it which is supposidly v1.0.1863.39252. (Which by the way took awhile to find and I'm still not sure if it is a complete download.) there is also no exception to this, and I am finding that even more types of files dont work and have this same error.
  
 
  
  
    thank you for providing these links, I couldn't find any other one besides filefront.
