Thread: Unable to install any application

Hi, Someone please help.
I have recently started using my wildfire s. Few days ago however when i opened my gallery, the gallery did not open however a messege came up saying that "Internal memory is low, please make some free space before using this application". I checked my settings and saw that there was only around 9MB free space left as internal storage.

Just after that, there was another messege asking me to clean application cache (I have no idea what is cache) to free some memory, I cleaned cache for 2 apps however the problem still remained. I then moved all my 4 apps to SD card but as an internal memory there is still 140MB full. I was then able to open my gallery.

And now the problem is, I can't install any application. When I do a messege comes up saying that "Insufficient storage available".
I have no idea whats wrong with it. Any help would be really appriciated.
Many Thanks in advance.
