Please give me a hand!

Dear all,  
  
I am a TRGpro user, and I've upgraded my OS from 3.5.2 to 3.5.3 a few days ago. Now the Chinese system I am using is ChOS(Version 4.02 for King's International's member). By the way, I also HotSync'ed "AutoCF" to my TRGpro a few days ago. My quesions are as below:  
  
1. Does ChOS support AutoCF?  
Because everytime I tried to launch "CardPro"(I wanted to  
move files from RAM to CF card), my TRGpro hangs. Once  
I disable ChOS first, then tried to launch "CardPro". It works!  
  
2. Or Palm OS 3.5.3 makes my TRGpro unstable?  
  
Please tell me that what should I do now!  
And thank you for your kindly reading my quesions.
