Hi. I am using MyEclipse 5.1 on WindowsXP (installed via the full stack installer). JDK1.5.

When I set my Windows Regional Options to "Thai" (which is what I use normally), and enter the key, MyEclipse said the key is expired. I have to change to English (United States) before it accepts the key as valid.

(I remember last year I had to do this also, but forget to report).

follow this link to see some more error messages.

The problem is that the calendar used in the Thai setting is not the Gregorian calendar and you need a commandline option to compensate. Please see this thread for the resolution: http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-6486.html
