You can get round this by aligning using Mothur from Pat Schloss, doing the alignment there and then merging it with the current Silva database.

You mention that you have a contigs file, which suggests that you're looking at metagenomics data, so perhaps you want to try something like MG RAST or PhylOTU which will get you phylogenetic information from a metagenomic rather than 16S dataset?

Silva seems nice but i have more than 300 sequences
