I can confirm that now the DBW 1.71 SuperPack installed successfully,
over the same UP3 RC4 as before.
It runs OK even for such a noob as I am.
Oops ! When starting the DBW171 SuperPack next time, the same error as formerly appeared, at the stage "Stand by -Loading tracks". When stock game selected, it runs well. Tried 512, 256 MB RAM.
Please, anybody who has it running well, can you say what is the size of il2fb.exe file after running the Selector ? Or upload that file for me, please ?
