Blur Build error

Hi, I have a shader error that might sometimes leave the game in a white screen. I have tried to fix it but I only seem to create more errors.

The error occurs on the for loop for me.

Shader error in 'DSS/UI/Blur': unable to unroll loop, loop does not appear to terminate in a timely manner (721 iterations) or unrolled loop is too large, use the [unroll(n)] attribute to force an exact higher number at line 131 (on d3d9)
Shader error in 'DSS/UI/Blur': unable to unroll loop, loop does not appear to terminate in a timely manner (45 iterations) or unrolled loop is too large, use the [unroll(n)] attribute to force an exact higher number at line 131 (on d3d11_9x)

Code (CSharp):

1.  
2. float2 pix = float2( 1 / _TexWidth, 1 / _TexHeight );
3.  
4. color = ((tex2D(_MainTex, IN.texcoord) + _TextureSampleAdd) * IN.color) / _Fineness;
5. //    #if SHADER_API_D3D9 || SHADER_API_D3D11_9X
6. //    [unroll(45)]
7. //    #endif
8. for ( int i = 0; i < _Fineness; ++i )
9. {
10.      half4 fcol = float4(0, 0, 0, 0);
11.      col += ((tex2D(_MainTex, IN.texcoord + float2(pix.x * i, 0)) + _TextureSampleAdd) * IN.color) * 0.125;
12.      fcol += ((tex2D(_MainTex, IN.texcoord + float2(pix.x * -i, 0)) + _TextureSampleAdd) * IN.color) * 0.125;
13.      fcol += ((tex2D(_MainTex, IN.texcoord + float2(0, pix.y * i)) + _TextureSampleAdd) * IN.color) * 0.125;
14.      col += ((tex2D(_MainTex, IN.texcoord + float2(0, pix.y * -i)) + _TextureSampleAdd) * IN.color) * 0.125;
15.      fcol += ((tex2D(_MainTex, IN.texcoord + float2(pix.x * i, pix.y * i)) + _TextureSampleAdd) * IN.color) * 0.125;
16.      fcol += ((tex2D(_MainTex, IN.texcoord + float2(pix.x * -i, pix.y * i)) + _TextureSampleAdd) * IN.color) * 0.125;
17.      fcol += ((tex2D(_MainTex, IN.texcoord + float2(pix.x * i, pix.y * -i)) + _TextureSampleAdd) * IN.color) * 0.125;
18.      fcol += ((tex2D(_MainTex, IN.texcoord + float2(pix.x * -i, pix.y * -i)) + _TextureSampleAdd) * IN.color) * 0.125;
19.      color += fcol / _Fineness;[/INDENT]
20. }
21.              
22. color.a *= UnityGet2DClipping(IN.worldPosition.xy, _ClipRect);
23.  

I tried adding the unroll but that seemed to create other problems. Hopefully someone have had a similar problem and can help me out. Cheers all.
