so that is it, really! I can't get past the preparing results page (or at least, I am not prepared to wait an undetermined amount of time!!!) I have tried doing everything the FAQ suggests (and unticking the display results and save results). Sometimes I get errors but at the moment I have 14 verified extensions and no errors. Under addon manager functionality I get the following errors...
Addon with GUID of {20a82645-c095-46ed-80e3-08825760534b} is reported by AddonManager but does not have an entry in the extensions directory
Addon with GUID of jqs@sun.com is reported by AddonManager but does not have an entry in the extensions directory
Addon with GUID of {FFB96CC1-7EB3-449D-B827-DB661701C6BB} is reported by AddonManager but does not have an entry in the extensions directory
Incidentally I have just re-installed this software hoping to give it a second chance as I had similar issues last time!
Any ideas?
