can't open version 0.74 to 0.79

OS: Windows XP Home Edition service pack 2 (5.1, Build 2600), (fully updated)

Security: Windows firewall

AntiVirus: Norton 2005

Computer: Presario V2000, AMD Turion 64 Mobile Technology ML-34, 512MB ram

Tried installing version 0.70 to 0.79, works fine up to 0.73.

for version 0.74 to 0.79, when trying to open them, it loads for a bit, but nothing shows up. Can see bitcomet running in task manager, but it will closes itself after awhile. The amount of CPU usage and memory usage is normal. No error pops up, bitcomet just never shows up and closes the process itself after awhile.

Currently still using the 0.70 since the 0.79 has the same problem even though it is already released as a stable version

Who told you it was a stable version?
