If I regularly search for a limited range of topics, such as “Aston Villa” in the documents section or “football,” I’m told the number of responses eventually dries up because Limewire thinks it is from a Spam merchant. Is there any way around this?

Below is a list of the info' I'm told you'll need to answer this question, as far as I can.
1. Windows XP Professional
2. What firewalls you have? XP
3. How much ram? 500
4. Hard Disk space available? 2.3 Gig
5. Connection type? Broadband
6. Modem & router brand name & model numbers? Belkin Gplus
7. Where are you trying to connect from home
8. What version of LimeWire (LW) & Java do you have? (Go to LW's menu Help bar > About LW...) Will show both LW & Java version. 14.4.12 Pro & 1.6.0_7
9. Who is your ISP (Internet Service Provider)?
10. Do this simple test for us. Using your browser go here: Yep it got 'Your test worked.”
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. NO
12. Is this a your 1st try at LW or is this a new problem with an experienced user.
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Yes_ click here to see Sample image
14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled?
15. What security programs are you using (antivirus etc)? Some people might not be aware that their security suite includes a firewall AVG 7.5
16. What country are you living in? Sometimes there are ISPs with the same name in more than one country UK
17. Has anything in your setup changed recently? Have you updated your version of LW or Java? Have you added any new software or new hardware? Have you updated any software? Have you moved house, changed internet plan or ISP etc etc? No

You can right click a search result after it stops searching and choose find more results, but apart from that I don't think there is much more you can do except search again.

BTW in this case it was a general Limewire question, so those thinks weren't really needed, but it's a joy to see that some people actually post the info we ask for

If it was a connection or download/upload problem, as in not able to download at all or most of the time, then they would be needed.

Cool thanks for this - I'll give it a go.
