What are your computer specs? I want Company, Model Number (Not serial Number) RAM, Processor, and did you install microsoft update (different that windows update, ive had the same problem as you, i fixed it by installing a newer processor, my celeron sucked)
Latest release ver works on my main desktop computer. Beta works on my other computer which is a laptop with a 64bit processor running Windows 7 Home Edition x64. Now my main desktop comp won't run the beta. It is a 32bit processor running Windows XP Home Edition. I hope this info will help your dev team to fix any bugs which may be preventing my desktop computer from running the true latest version of the software (the one which is currently a beta).
