Ok, I discovered next problem with ESS. It seems that some of the last virus or module ESS update (AH again?) is blocking FreeRapid Downloader from starting - only splash screen briefly flashes - it's java application. http://wordrider.net/forum/read.php?7,414 I can confirm, that it worked few days ago and it's working on PCs without ESS. NOW on every PC with ESS installed it will fail to start. Disabling firewall and virus protection did not help - only killing ekrn.exe. Can someone confirm it and again - can ESET fix it? Thanks. Regards Tom UPDATE: Problem is confirmed, FRD will fail to start when feature "Allow only one instance" is enabled in FRD settings. ESS will block the only one instance check. Workaround: Start FRD with this switch: frd.exe -Doneinstance=false (for example change your shortcut). This will disable the problematic function.
