Crap!
 

Why did I ever purchase LimeWire Pro? The free version works better! Now I get the 'Not connected to gnutella network, you may not get many results'! What the hell is this about? I'm a very unsatisfied user! Do something!

The Pro and Basic version are the same! If you can't connect with the Pro version you can't connect too with the Basic version. The difference is only in the maximum number of connecitons it will perform simultaneously.
Redownload a newer version. Many things have changed recently, including on Windows since XP SP2 has been released or many antivirus and firewall softwares have been updated.

LimeWire is currently evolving to take these evolutions into account (and both the Basic and Pro versions are affected by those changes), and builtin support for UPnP and NAT routing in Limewire is currently in beta (because users have lots of difficulties in configuring the Windows XP's builtin firewall, and more and more DSL modems include support for "UPnP" with firewall and NAT mode enabled by default and configurable only through the UPnP interface that users don't understand how to configure correctly):

Notably this applies to lots of WiFi hotspot routers, or to NumericTVchannels+Phone+Internet blackboxes provided by ISP and that nearly always include now a NAT router.

The combination of an external NAT router and an internal firewall in Windows XP SP2 is the most complex case to configure correctly for average users. This is not the fault of LimeWire, but without UPnP supported in Windows XP and in external NAT routers (add to this the difficulties to configure the "ZeroConfig" parameters for the WiFi gateway...) this is a nightmare to configure correctly (and many users are unable to set the parameters correctly in their router or in the Windows XP Firewall control panel), because users are lots within multiple IP interfaces and addresses.

So LimeWire is now supporting its own UPnP agent (and also includes now its own DNS client, bypassing the Java and OS implementations, and its own HTTP protocol handler to use this DNS resolver).

May be in a near future, Limewire will also need to support multiple IP interfaces for Internet accesses: UPnP will also be the key for this implementation, allowing managing completel internal IP routing tables in LimeWire (also needed to support IPv6 later). Prior to UPnP, there was no standard to allow configuring routers (the SNMP protocol existed but was only standardized for read-only access, and nearly never available in small hardwares; since UPnP is now available, interoperable schemas for SNMP are standardizing too, and LimeWire may include an SNMP agent if needed).
