That's a Java error... I don't think there's anything suspicious about it

Euclid Networks is connected to or is the same as Euclid Networks Inc, which may be connected to Euclid Inc, this being a company begun by Andra Delip Kumar, CEO of Euclid India Ltd. although it is reported that Rao Cherukuri is the founder and chairman of Euclid Networks. Then there is also, or was, Euclid Network Solutions Inc. Read about the company at http://www.rediff.com/computer/1999/ oct/16euclid.htm . A news report from Bangalore some years ago reported that “network service provider Euclid India Ltd. is to merge with the US-based Euclid Network Solutions. This will make the Indian company a wholly-owned subsidiary of the US firm. Clearance from the Foreign Investment Promotion Board is awaited” A common theme of sites run by Euclid Networks is the lack of any contact details until money has changed hands. It would appear to be connected with:
NetFreeMovies.com
TV-All-Free.com
NetFreeGames.com
NetGamesNow.com
AccessMp3Music.com (which describes itself as “the largest p2p network”)
FreeAccessMp3.com
iMusicAccess.com
iMusicNow.com
Mp3-All-Free.com
Mp3JustFree.com
Mp3RealMusic.com
MusicJustFree.com
NetFreeMp3.com
Download-it-free.com
A company called YottaCash.com is a wholly-owned and operated arm of Euclid Networks.
All these companies seem to have the same theme but you have to read the small print - they provide (or tell you how to get) other organisation’s programs, including Limewire, and charge you for the privilege. The small print on ‘Movies-All-Free” for example has a clause “The software is free. You are paying for the online help and support and the online tutorials for the lifetime of the membership”(the 'lifetime' time of the membership is not given). The trouble is that when you are looking for Limewire for the first time and you come across one of these sites you don’t know its not the right site; by the time you do you have paid your money. There is also a similar site, Mp3MusicDownload, where the footer reads “Legal Advise about using P2P networks and Disclaimer, Billing by SOP R&M, St-Kitts, BasseTerre, 1823 Bay Road.”. Note the misspelling of the word “Advice” and the fact that they are from the same street as Euclid Networks. Another company using the same address, 1823 Bay Road, Basseterre is Nextdaysoma.com, an on-line drug company. The address may be a PO Box - the billing for Nextdaysoma.com goes to Manama International Limited, C18 The Sands, PO Box 1823 Bay Road & George Street, Basseterre St. Kitts. The telephone number 1- 888-846-9590 at the start of this thread is the same number as that used by a company called Downloadinghome.com, a site owned by Mp3Networks, St Kitts.
