EclipseFP issues with Hoogle

Question

Installed EclipseFP, looks without any observable issues. However, when I start Eclipse, I get this:

Whether I click yes or no, the same thing happens on next restart.

Also, in the Hoogle view, I see this:

even though I see the databases seemingly OK in workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.browser\scion-browser-0.2-dbs:

hackage.db  123.71 MB   31.10.2014 09:42:18 Data Base File  A
local.db    3.06 MB 31.10.2014 10:20:53 Data Base File  A

In the scion-browser console, I have this on startup:

>> {"rebuild":true,"filepath":"C:\\eclipse\\workspace\\.metadata\\.plugins\\net.sf.eclipsefp.haskell.browser\\scion-browser-0.2-dbs\\local.db","command":"load-local-db"}
Local database loaded
"ok"
>> {"module":"","command":"get-modules","db":"_all"}
>> {"rebuild":false,"filepath":"C:\\eclipse\\workspace\\.metadata\\.plugins\\net.sf.eclipsefp.haskell.browser\\scion-browser-0.2-dbs\\hackage.db","command":"load-hackage-db"}
Hackage databas"ok"
e loaded
>> {"module":"Prelude","command":"get-declarations","db":"_all"}
>> {"path":"C:\\eclipse\\workspace\\.metadata\\.plugins\\net.sf.eclipsefp.haskell.ui\\sandbox\\.cabal-sandbox\\bin\\hoogle.exe","command":"extra-hoogle-path"}
"ok"
>> {"command":"hoogle-check"}
C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin\hoogle.exe

"Error"

Looks like hoogle is not working from the command line either:

C:\>cd C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin\

C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin>hoogle fmap
Could not find some databases: default
Searching in:
  .
  C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\x86_64-windows-ghc-7.8.3\hoogle-4.2.36\databases

There are no available databases, generate them with: hoogle data

C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin>

Any ideas here? I'll add additional information as needed, just not sure what would be useful, let me know and I'll edit.

Looks like for some reason hoogle did not work from the command line either. May be related to this:

C:\eclipse\workspace\.metadata\.plugins\net.sf.eclipsefp.haskell.ui\sandbox\.cabal-sandbox\bin>hoogle data
Downloading downloads/platform.cabal

hoogle: Error when running Shake build system:

Could not find downloader, neither curl nor wget are on the $PATH.

I have Cygwin installed, so I fixed this by running hoogle data from withing Cygwin terminal, which had wget available in the path and that seems to have solved the issue.
