I upgraded to version 2008 and all was well. Then upgarded to latest version 449 and when the program is launched, all that happens is the cursor blinks off, comes back and nothing, it is as if the program did not load at all. OS is xp 64 pro.

Having identical problem from Quick Launch Bar. 1st Click some hor glass indication then nothing. Double Click and program launches, sometimes with two running copies. Xp home SP2, AMD Athlon 64x2 dual. 4200+ 1.00 GB RAM

Same here. The program will not execute using Vista Ultimate (64 bit).

the same is true with me as well xp 64 pro

Exact same problem. Vista Ultimate x64 SP1

Thank you for reporting. This problem should now be fixed, the fixed version will be released in next week, hopefully on Monday or Tuesday.
